Can't create user data folder when project name has ``\ / : * ? " < > |`` characters on OS_Windows & OS_Unix.
So, change it to ``-`` to be able to make folder.
fixes#4928 and it's altanative to #4986.
They were wrongly placed, creating a file named "-fpic" instead of
applying "-fpic" to the build. This file was in .gitignore, which made it
less noticiable.
This also adds build.gradle to .gitignore.
-Rearrange favorites in fs dock with drag and drop
-Removed import -> sub-scene, moved to scenetree contextual menu
-Removed import -> re-import , moved and integrated to FS dock
-Added ability in FS dock to re-import more than one resource
simultaneously
-Added ability to drag from native filesystem explorer to Godot, only
works on Windows though
-Removed scene reimport merge options, never worked well. Eventually
merging materials should be re-added
-Added ability to set custom root node type when importing scenes
-Re-Import is now automatic, can be configured back to manual in editor
settings
-Added resource previews in property list for many resource types
using ``NotificationCompat`` in ``support-v4`` library will increase APK filesize a little bit, but it guarantees to run OK with API 4+
tested with API 19 and 23 devices
If we update build gradle to use ``compileSdkVersion 23``,
``org.apache.http`` package causes error. (issue #4711)
We need to use ``useLibrary 'org.apache.http.legacy'`` to solve this problem.
To use ``useLibrary``, we need to use latest gradle also.
And now, we faced another problem with ``APK Expansion`` java sources.
```
/platform/android/java/src/com/google/android/vending/expansion/downloader/impl/DownloadNotification.java
137 : mCurrentNotification.setLatestEventInfo(mContext, mCurrentTitle, mCurrentText, mContentIntent); // causes error
```
So, some of APK Expansion java sources are updated by referencing commits from https://github.com/danikula/Google-Play-Expansion-File
And dropped V3CustomNotification.java which was for android 3.0, since godot supports android 14 (4.0) above officially.
Unfortunately, another problem, The 'MissingTranslation' error was occurred.
So, build.gradle is updated to use ``disable 'MissingTranslation'``
Additionally, I updated ``buildToolsVersion``, ``targetSdkVersion`` to latest version.
I tested APK Expansion funtionality on Android 6.0 (Nexus 9, Nexus 6p) and Android 4.4 (Galaxy Note 2) with Google Developer console.
