Improve spritebank slightly (more comfort functions and documentation).


git-svn-id: svn://svn.code.sf.net/p/irrlicht/code@4751 dfc29bdd-3216-0410-991c-e03cc46cb475
Mention in documentation that getSpriteBank currently doesn't load files (that's never been implemented).

Backport r4723 from trunk:
Fix c::b project obj folder names. Some static builds had used the shared folders (thx @ gerdb for reporting)

Spritebanks can now draw scaled sprites.

IGUIEnvironment::hasFocus can work with a const pointer.

Buttons can now now have 7 more image-states, 1 more sprite-state and the sprites are now scaleable.

Remove lot's of setFocus and removeFocus calls. Also several places where elements check if they have the focus inside events.
Slightly risky change - but it's hard to improve all this without cleaning it up first. And most elements should _not_ be responsible for their 
own focus but the guienvironment should do that (and does do it).
