Make gettors for class Settings const

Also removed 2 unused functions
All I did was reformat the line. The ternary operator is hard to read if the ? and : are placed as they were earlier. I have no interest (at this stage) in changing the logic of the code or even looking at it except for making the get* functions const correct.

If you are talking about the strange indent then, yes, I didn't mean to do that. The ? and the : should probably be on their own lines since it doesn't all fit on one (80 char) line.
