Optimized QuadBatch2D class, in particular renderCustom().
Optimized GPURenderCanvas to only color images if mix alpha is below
1.0.
Replaced event handling in Stage3DProxy class with signal handling.
Deleted Stage3DEvent class.
compiled swc.
Adapted project to AIR SDK 3.6 and ASC 2.0.
Disabled Preloader for now in Entry class template.
Updated build files to work with AIR SDK 3.6/ASC 2.0. I've added
marcodefs that use Ant's exec instead of relying on Adobe's mxmlc Ant
taks. With these all compiler arguments are supported. The mxmlc task
doesn't seem to support the -frame argument (yet) which however is
necessary to implement a proper preloader mechanism.

I've added two different marcodefs, one for web builds, the other one
for AIR builds. This way the SWFs are built more efficiently (and AIR
builds don't need the -frame arg since they don't need a preloader).
Changed Render2D instance to be obtained via ScreenManager.
Fixed the preload mechanism for web builds to work again with the ASC
2.0 compilation.
Removed ASC2 unsupported arguments from fdt_desktop.launch file.
compiled dist file.
