[EditorExportPlugin]s are automatically invoked whenever the user exports the project. Their most common use is to determine what files are being included in the exported project. For each plugin, [method _export_begin] is called at the beginning of the export process and then [method _export_file] is called for each exported file.
To use [EditorExportPlugin], register it using the [method EditorPlugin.add_export_plugin] method first.

Add support for scene/resource customization in export plugins
EditorExportPlugin adds a set of callbacks to allow customizing scenes, resources or subresources in all files exported:
* Can take scene files, resource files and subresources in all of them.
* Uses a cache for the converted files if nothing changes, so this work only happens if a file is modified.
* Uses hashing to differentiate export configuration caches.
* Removed the previous conversion code to binary, as this one uses existing stuff.
This API is useful in several scenarios:
* Needed by the "server" export platform to get rid of textures, meshes, audio, etc.
* Needed by text to binary converters.
* Needed by eventual optimizations such as shader precompiling on export, mesh merging and optimization, etc.
This is a draft, feedback is very welcome.

Virtual method to be overridden by the user. It is called when the export starts and provides all information about the export. [param features] is the list of features for the export, [param is_debug] is [code]true[/code] for debug builds, [param path] is the target path for the exported project. [param flags] is only used when running a runnable profile, e.g. when using native run on Android.

[param path] is the path of the file, [param type] is the [Resource] represented by the file (e.g. [PackedScene]) and [param features] is the list of features for the export.
