editor window title improvements

Shows the project name in the window title (good to differentiate multiple instances of Godot with different projects loaded).

Clears the previous scene name from the window title when creating a new scene.
-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

editor window title improvements
use Snap / Snap (Pixels) now save to scene file

Previously, only Use Pixel Snap would save to the scene.
Tested and working for me, on Linux.
added bindings for InputMap
stops running process when quitting editor

I noticed a bug where I could close Godot while I was running a project.

If the program was left running and then ran into an error,
or if an error was caught by the debugger and then I quit Godot,
I could no longer close the running project without manually killing it.
This fixes that problem by essentially hitting the Stop button automatically
just prior to quitting the editor.
