Coding Conventions Consistency

[cburgard]

The current coding convention is inconsistent - sometimes, getter functions are named "getX()" [Tile], while sometimes they are simply called "x()" [DieState].

right. what should we set up?
I vote for "x()".

additionally, sometimes there are tabs instead of spaces in the code.
depending on editor settings, that may scramble indentation.
trying to get rid of them while looking through the code, though.
