Re: triggering FontForge re-runs

This is a feature that we're hoping to implement in the future, but there
are a number of technical challenges, mostly relating to the multi-file
arrangement of U. F. O. and the time required to reload a large U. F. O. in
its entirety (probably requiring that we support partial reloading).

I hadn't thought about it before, but there are a lot of things, like an
open TrueType debugging session or even just a standard dialog, that might
break a reload. The rough way to deal with this would be to force a
close-open cycle at reload, but this doesn't provide an optimal user
experience.
