- Bug fix: at osx, default AA font couldnt be written in .b.blend

(unless you manually install font)
- Bug fix: string for AA font was only 64 chars... made 256.

- Changed API for buttons aligning... it now detects automatic what rows
  are, or collums, and aligns buttons. This makes call easier:
  uiBlockBeginAlign(block);
  ... defBut....
  uiBlockEndAlign(block);
  Only works when you provide buttons in row order!
- made sure only 'rounded' theme uses this align stuff
- still work in progress.. I commit now because I leave to denmark for 2 days!
