-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
