CCDraw: add possibility to use background images as item background

Browse Source 
Provides functionality to use a backround image instead to render
usual box. If an image is defined, box render is disabled, but behavior
for hide, kill, cache... is not changed.

TODO:
- maybe needs global caching because images are not yet managed like icons in framebuffer class
