Add support for different coding styles

It is strange, that Qt Creator still haven't support extended code formatter like other IDE does (for example, Eclipse – http://www.wikihow.com/Change-the-Default-Format-Settings-in-Eclipse).

As for me, that is lack of K&R codding style (http://en.wikipedia.org/wiki/Indent_style#K.26R_style).

Here is question on StackOveflow on this theme: http://stackoverflow.com/questions/17841984/change-brace-coding-style-in-qt-creator

It would be great to have this feature in Qt Creator 3!
