New and improved IK system for Skeleton3D
This PR and commit adds a new IK system for 3D with the Skeleton3D node
that adds several new IK solvers, as well as additional changes and functionality
for making bone manipulation in Godot easier.
This work was sponsored by GSoC 2020 and TwistedTwigleg
Full list of changes:
* Adds a SkeletonModification3D resource
* This resource is the base where all IK code is written and executed
* Adds a SkeletonModificationStack3D resource
* This node oversees the execution of the modifications and acts as a bridge of sorts for the modifications to the Skeleton3D node
* Adds SkeletonModification3D resources for LookAt, CCDIK, FABRIK, Jiggle, and TwoBoneIK
* Each modification is in it's own file
* Several changes to Skeletons, listed below:
* Added local_pose_override, which acts just like global_pose_override but keeps bone-child relationships intract
* So if you move a bone using local_pose_override, all of the bones that are children will also be moved. This is different than global_pose_override, which only affects the individual bone
* Internally bones keep track of their children. This removes the need of a processing list, makes it possible to update just a few select bones at a time, and makes it easier to traverse down the bone chain
* Additional functions added for converting from world transform to global poses, global poses to local poses, and all the same changes but backwards (local to global, global to world). This makes it much easier to work with bone transforms without needing to think too much about how to convert them.
* New signal added, bone_pose_changed, that can be used to tell if a specific bone changed its transform. Needed for BoneAttachment3D
* Added functions for getting the forward position of a bone
* BoneAttachment3D node refactored heavily
* BoneAttachment3D node is now completely standalone in its functionality.
* This makes the code easier and less interconnected, as well as allowing them to function properly without being direct children of Skeleton3D nodes
* BoneAttachment3D now can be set either using the index or the bone name.
* BoneAttachment3D nodes can now set the bone transform instead of just following it. This is disabled by default for compatibility
* BoneAttachment3D now shows a warning when not configured correctly
* Added rotate_to_align function in Basis
* Added class reference documentation for all changes

This node will allow you to select a bone for this node to attach to. The BoneAttachment3D node can copy the transform of the select bone, or can override the transform of the selected bone.
The BoneAttachment3D node must either be a child of a [Skeleton3D] node or be given an external [Skeleton3D] to use in order to function properly.

<method name= "get_external_skeleton" qualifiers= "const" >
<return type= "NodePath" />
<description >
Returns the [NodePath] to the external [Skeleton3D] node, if one has been set.
</description>
</method>
<method name= "get_override_mode" qualifiers= "const" >
<return type= "int" />
<description >
Returns the override mode for the BoneAttachment3D node.
</description>
</method>
<method name= "get_override_pose" qualifiers= "const" >
<return type= "bool" />
<description >
Returns whether the BoneAttachment3D node is overriding the bone pose of the bone it's attached to.
</description>
</method>
<method name= "get_use_external_skeleton" qualifiers= "const" >
<return type= "bool" />
<description >
Returns whether the BoneAttachment3D node is using an external [Skeleton3D] rather than attempting to use its parent node as the [Skeleton3D].
</description>
</method>
<method name= "on_bone_pose_update" >
<return type= "void" />
<argument index= "0" name= "bone_index" type= "int" />
<description >
A function that is called automatically when the [Skeleton3D] the BoneAttachment3D node is using has a bone that has changed its pose. This function is where the BoneAttachment3D node updates its position so it is correctly bound when it is [i]not[/i] set to override the bone pose.
</description>
</method>
<method name= "set_external_skeleton" >
<return type= "void" />
<argument index= "0" name= "external_skeleton" type= "NodePath" />
<description >
Sets the [NodePath] to the external skeleton that the BoneAttachment3D node should use. The external [Skeleton3D] node is only used when [code]use_external_skeleton[/code] is set to [code]true[/code].
</description>
</method>
<method name= "set_override_mode" >
<return type= "void" />
<argument index= "0" name= "override_mode" type= "int" />
<description >
Sets the override mode for the BoneAttachment3D node. The override mode defines which of the bone poses the BoneAttachment3D node will override.
</description>
</method>
<method name= "set_override_pose" >
<return type= "void" />
<argument index= "0" name= "override_pose" type= "bool" />
<description >
Sets whether the BoneAttachment3D node will override the bone pose of the bone it is attached to. When set to [code]true[/code], the BoneAttachment3D node can change the pose of the bone.
</description>
</method>
<method name= "set_use_external_skeleton" >
<return type= "void" />
<argument index= "0" name= "use_external_skeleton" type= "bool" />
<description >
Sets whether the BoneAttachment3D node will use an extenral [Skeleton3D] node rather than attenpting to use its parent node as the [Skeleton3D]. When set to [code]true[/code], the BoneAttachment3D node will use the external [Skeleton3D] node set in [code]set_external_skeleton[/code].
