Only invalidate cache if data actually changes

Added my first stab at native.BitmapData.threshold() function. Still has some small glitches (inconsistent results with flash's, could be optimized).
native.Bitmap: when bitmapData == null, it should clear its graphic.
Removed "--js-modern" for html5 hxml, since it became default behavior and the option was removed from haxe3.
Fix startup issue where event is not set first time around

BitmapData.threshold seems accurate now, and decently fast, too!
Trying to test native build of NME using Travis.
Travis cannot install ia32-libs-multiarch...
Travis: NME is installed in cwd.
Travis: use a dummy audio.
Added copyFrom and setTo to Vector3D (both native and browser).
Adding TravisCI unit-test for cpp, neko and js target.
Merge branch 'master' into travis-native
TravisCI: Remove the 16-Memory sample.
It is actually crashing...
cpp BitmapData.threshold() now passes these tests:

-Basic functionality
-Decently optimized for straight "==" palette swapping
-Returns same # of pixels changed as flash target
-Returns same visual output unless you mess with destPoint
(will figure out destPoint later)
Forgot a line!
Fixed return value on threshold(), also destPoint seems to work now
TravisCI: basic skeleton of supporting test in plain haxe and in NME.
