ASFont: Refactored string drawing methods.

Browse Source 
Renamed methods that draw a single line from write() to writeLine().
There is now only one write() method left: the public method.

Pass surface to draw on as wrapped Surface instead of SDL_Surface.
At the end of the call chain we still use SDL directly though.
