[Zope] I hate counters...

...but I was loading a (really) old site which used them so I needed the functionality. Andym's FScounter has a good feature set but it was missing the ability to set the counter to an arbitrary value (to pick up from where the old site left off). So I modified andy's counter (http://www.zope.org/Members/bowerymarc/FScounter) to do that, and I included a default digit set, with a .zexp to make it easy to install.
