For 0.7:
- make Bugzilla methods all take a bug ID list
  - BZ 3 methods all take idlist
  - RHBZ can use multicall to emulate that
- Add .legal_values() method to Bug object

General:
- i18n for strings!
- Fix up selftest.py (it's a big fat mess)
  - Actual unit tests would be a better idea.
- better documentation for abstract methods in BugzillaBase
- more consistent calls for abstract methods. 
  - fix bz.createbug(description=desc,...) vs. bug.close(comment=desc,...)
  - use field_aliases to fix up bug.close and friends?
- make the abstract methods return stuff closer to Bugzilla3's return values
- Document the 0.x API as it stands
- Work on a cleaner 1.x API
