Renaming the prefs struct members to be consistent with the QSettings.

-Renaming prefs members for consistency.
-Changing references of QSettings to the prefs structure instead.
-Removing unused functions in pref.h were left over from an old version.
-Changing the data-type of bool members to short for consistency with other members.
