2013-11-01 New control positioning method

this commit adds a new way to position controls on screen.
- <left>
- <top>
- <right>
- <bottom>
- <centerleft>
- <centertop>
- <centerright>
- <centerbottom>



on top of that, it also allows you to use percentages instead of absolute values.

note: the old way (posx/posy/width/height) will still work in gotham
note: for label positioning to work correctly, defaults.xml should have no position defined for label.

for more info, please use the forum thread below.
