0.2.1 released

[renanse]

0.2.1 has been released, bringing with it our first public release of the source code. Since pretty much everything is new for those just joining us, I will simply mention some highlights since our internal 0.2 release:

- Particles were ported from my work on jME.
- Math package objects were refactored to remove the mutable flag and to make use of a Readable* interface, thus allowing us to ditch defensive copying in many places. (yay!)
- Jogl - AWT input was fixed.
- Source is now broken up into separate projects with project sets importing.
- Primitive counts and vertex - index access for multi-part mesh data is now correct.
- Lots of other small tweaks and bug fixes.
