Making Godot Easier to Use.. -=-=-=-=-=-=-=-=-=-=-=-=-=-= -Auto indenter in code editor, this makes it much easier to paste external code. -Zoom in 2D viewport now uses the mouse pointer as reference. -Obscure hack to see where code/line of GDScript in C++ backtrace. -Fixed a bug where keys would get stuck on X11 if pressed simultaneously -Added Api on IP singleton to request local IPs. -Premultiplied alpha support when importing texture, editing PNGs and as a blend mode.

-Added google play services (needed for some stuff) -Added new screen resizing options, stretch_2d is removed, new much more flexible ones. -Fixed bug in viewport (can create more instances in 3d-in-2d demo now) -Can set android permissions and screen sizes manually in the export settings -Changed export templates extension to .tpz (too many people unzipped the manually..) -File dialog now ensures that the proper extension is used (will not allow to save without it) -Fixed bug that made collision exceptions not work in 2D
