Converted more of the modules to haxe--enough for Nomltest to work!

Fixed the l$r and &LABEL syntax to allow extra whitespaces, as is used in the Nomltest script.

Fixed CMLMovieClip.copyTexture() to deal with alpha blending properly.

Added temporary joystick support to CMLMovieClipControl.

Switched some (though not yet all) imports to use openfl instead of
flash.

Renamed CMLMovieClipScene to CMLMovieClipSceneManager to more
accurately match what it does.

Added CMLScene as a base class for scenes handled by the
CMLMovieClipSceneManager.

Fixed some crashes found by testing Nomltest.

Removed some unnecessary debug output.

Added an exception for trying to create an Actor not derived from the
Actor class.
