Make GF values configurable

There are a couple of issues with this commit:

GtkEntry should emit the 'changed' signal when it is modified (so that
changes in the preferences get applied right away) - but that doesn't
appear to be working consistently.

Also, this doesn't appear to affect the deco of any dives that I try it
with. So my guess is something is wrong with the underlying deco
algorithm. That's diappointing.
