Bug fix with HUD for github issue #60
GitHub issue #38: update dirty textures WebGL

Issue: TextureAtlases not updating upon dirty being toggled

Fixed by adding a “dirty check” to the rendering pipeline directly
before draw calls.

Added TextureAtlas.refreshTextureGL method for more transparent texture
updates. This should be compatible with future additions to the engine,
for example, a form of atlas that stores both colour and normal data.

Standardised non-batch render calls to use identical process. The only
non-batch renderer at this time is in the WebGLParticlePlugin, which
does a lot of its own heavy lifting. We’re trying to standardise all
that stuff for future engine enhancements, so it will be easier to
write new renderers.
Updated docs and readme file for 1.0.1
Updated readme with missing error log.
Upgraded projects and grunt to typescript 1.0.0.
