Typo fixes
BitmapFontCache setColor changed to match SpriteBatch/SpriteCache.

Old setColor methods renamed to setColors. Note setColors may soon be changed to something better.

Changes
Fixed label pref size when using font scale.

http://www.badlogicgames.com/forum/viewtopic.php?f=11&t=12126&p=54427#p54427
Widgets now use setSize instead of setWidth/Height.

This avoids computing the pref size twice, since setWidth calls sizeChanged which invalidates.
Should not have been committed.
Fixed up some uses of BitmapFontCache setColor that should be setColors.
