Cleaned up some formatting issues.
Added some error checking.
Added compile scripts option to IDE export project window.
Removed duplicate include.

Numberous resizing improvements to UI controls and IDE props. Added DefaultShaderNoTextureHDR shader to hdr pack. Added a default REMOVE_EVENT Event type. Added Vector2 shader prop.
