Made sure files in core/ and tools/ have a proper Godot license header
when written by us. Also renamed aabb.{cpp,h} and object_type_db.{cpp,h}
to rect3.{cpp,h} and class_db.{cpp,h} respectively.
Also added a proper header to core/io/base64.{c,h} after clarifying
the licensing with the original author (public domain).
That year should bring the long-awaited OpenGL ES 3.0 compatible renderer
with state-of-the-art rendering techniques tuned to work as low as middle
end handheld devices - without compromising with the possibilities given
for higher end desktop games of course. Great times ahead for the Godot
community and the gamers that will play our games!
pop_front, pop_back now return values instead of `void`. Things
I didn't know how to properly implement:
1. pop_front & pop_back shows in the help menu Object as return value.
I know this is incorrect but if not Object than what? Cause it
can't be void. It needs to be a generic type that includes all the
Array types
