Adds a utility class converting ints to Roman numerals.
RomanNumber: Changed package name from counter to util.
Created new PlayerControl

Created a PlayerControl based on normenhansen's BetterCharacterControl
available in the nightly build. I used the source code for that and the
AbstractPhysicsControl, and the result works in the stable build as
well. Walks and jumps sluggishly.
Merge branch 'PlayerControl' of https://github.com/forssenm/kandidat-projekt into PlayerControl
