Fixed clamp method in ColorRGBA.
Merge pull request #158 from Perjin/colorRGBA-bugfix

Fixed clamp method in ColorRGBA.
thanks to Perjin
Added a version of createFloatBuffer that takes
a ColoRGBA array.
Implemented accurate bounding sphere to triangle
collision.  The old code had an implementation but
it missed tons of cases.

For 100,000 random points, the old way would process
that in about 12+ ms.  The new way does it in about
18+ ms... but the old way missed 643 collisions
(180 versus 823).

Plus, with the new way accurate contact normal and
contact point can be provided trivially... so it is.
Fixed an accidental sharing of temp vars vects
that turned out to matter.
Fix for proper collision distance based on 
precedent.  "I had one job..."
