Solved a minor issue concerning the external modfolders.

If you see external folders added twice, just delete the non-lower case entry.
There where 2 basic issues.
1) the external folders are saved on a "per game" basis, however checking if a folder allready existed didn't take game into account.
2) the external folders where saved exactly like they where (no upper or lower casing) this could lead to duplicate addonfolders (if you changed casing in the folder name).
