prefs: spelling fix, simplify code

Found spelling error "a another". All those dynamic allocations and
magic numbers are horrible and unnecessary. Simplify the gtk code
rewording the message and merging strings.

Simplify the version code by using fscanf to take care of matching
the first line of a preference file.
