Bug #638543: Add a GUI for the counter format and current value.

Patch by Matthijs Kooijman:

This allows the user to change the format used for the various counters,
as well as see and change the current value of the counter.

This is a bit of hack right now, since the format and current counter
values are stored in the counter_formats and counters kvp slots
respectively, instead of options/<section> like the other options in the
File->properties window.

This is implemented by adding the make-counter-option and
make-counter-format-option, which both replace the scm->kvp and kvp->scm
functions defined by make-number-range-option and make-string-option
respectively. The replaced function simply ignores the "path" parameter
and instead saves to the "counter" or "counter_formats" slot hardcoded.
