Avoid Vector/Array push() method about ash

Needs more investigation. Seems the arrays are only allocated when running air on mobile.

This is now confirmed. When running an Air app on mobile all functions with the ...rest parameter will allocate an array. For example calling ComponentPool.dispose() uses .push() which in turn allocates an array, nullifying the point of the call. As allocating as few objects as possible is most important on mobile I suggest this is fixed.

You can for example see Starling doing this in some places:

I do it in mvcExpress in all places instead of push. It is a bit faster. (not much..)
