Welcome in 2017, dear changelog reader! That year should bring the long-awaited OpenGL ES 3.0 compatible renderer with state-of-the-art rendering techniques tuned to work as low as middle end handheld devices - without compromising with the possibilities given for higher end desktop games of course. Great times ahead for the Godot community and the gamers that will play our games! (cherry picked from commit c7bc44d5ad9aae4902280012f7654e2318cd910e)

Misc Fixes ========== -NOTIFICATION_WM_QUIT fixed on android (seems tha way this is reported changed in newer sdk) -WIP implementation of APK Expansion APIs for publishing games larger than 50mb in Play Store -Feaures in the new tutorials are all present in the sourcecode -This (hopefully) should get rid of the animation list order getting corrupted -Improved 3D Scene Importer (Skeletons, Animations and other stuff were not being merged). Anything missing? -In code editor, the automatic syntax checker will only use file_exists() to check preload() else it might freeze the editor too much while typing if the preload is a big resource -Fixed bugs in PolygonPathFinder, stil pending to do a node and a demo

Add missing argument names in GDScript bindings All classes were reviewed apart from VisualServer for which no argument name is documented at all. While doing this review, I found quite a few bugs that were fixed either in earlier commits or this one (mostly documentation bugs though, i.e. some arguments were listed at the wrong place).
