-variables with export in script are now IMMEDIATELY AND ALWAYS visible in properties (#718)

-WorldEnvironment cleanup issues fixed (#563)
-Text Editor improvement to shift-mouse selection (#648)
-(Hopefully) fixed rare (but horrible) indexing bug in GDScript compiler (#652)
-Some changes to PhysicsBody API, renamed property "active" to "sleeping", which makes more sense
-Added add_collision_exception() API in PhysicsBody (more accessible)
-ability to select and copy in the output messages panel
