Add CCAction support

[andrew0]

I'd like some sort of support to add CCActions, but I'm not really sure how I'd want to implement that visually. Hopefully someone can come up with something eventually

I would love it if you could set an action on a node, with a start position and an end position (the end is what is shown in the preview). Basic support for Move/Fade actions and method: Slide, linear, easein/easeout, (bounce).

For example:
I choose a sprite and give it a Start animation:

• When the layer becomes visible, the sprite starts outside the screen, on the gived position.
• Then during 1 second animate in the sprite with EaseOut until correct position.

I would just start with the basics in the beginning, just allow some predefined animations:

• Move or Fade
• Linear, Easein, Easeout, Easein/out, (bounce)

The most important would be animate-in, but one could also build support for animate out very easly too.

With simply this you could build powerful menus!
