Thinking about building a custom install …

Thinking about building a custom installer if we get time. Should be run immediately after the core WPMU install (ideally would handle that install, plus the custom stuff, but we'll see what have time for). Should handle integration with bbPress, configuration of all plugins etc. Selecting which plugins are actually active would still be good to allow via the admin UI (so they can, for example, disable Polls or Events, or whatever.
