gitk: add text wrapping preferences
Add a new preference "wrapdefault" which allows enabling char/word wrap.
Impacts all text in the ctext widget for which no other preference exists.
Also make the (existing) preference "wrapcomment" configurable graphically.
Its setting impacts only the "comment" part of the ctext widget.
