Adds migrations for components, enums, and milestones.
Also fixes the javascript in the HTML pages to actually work.
Pluralizes the configuration page names.
Bump the version to 1.1.2 for the hell of it.
Kill some trailing space I noticed that didn't belong (didn't hurt anything, but I don't like unnecessary trailing space).
Add an All option for wiki pages - yeah, a blank prefix works, but it's non-obvious.
I just realized I forgot to put copy_milestone into all for util.py. Apparently it doesn't actually matter, since it works just fine, but you may want to stick that in there.
