* Fixed. CAAT.Foundation.UI.Label dependencies.
* Fixed. CAAT.Foundation.Actor dependencies.
* Added. Capture skeletal animation on-the-fly to an spriteSheet.
Reversed change from 0.6 build 52 as it breaks auto scaling of scenes/actors etc (director.enableResizeEvents)
Added removeScene and findScene methods. Changed setScene to accept either scene index or scene object.
If a CatMulRom is not closed, duplicate the first and last points to let it build the curve correctly
Made compile scripts a bit more friendly to other developers by moving all configuration variables to 1 single script
removed unreachable code
small change, let closure compiler find the build dir configured in variables script
Optimization: re-use inverse matrix objects instead of letting getInverse() create an inverse every single animation frame
Further optimisation, removed unneeded assignment of inverse matrix and added optimisation to ActorCSS as well
Merge remote-tracking branch 'hyperandroid/master'
