Added Bug.extra_strings to support add-on functionality, e.g. `be tag`.
Versioned properties whose data is a mutable type are tricky, since the simple comparisons we'd been using in libbe.properties.change_hook_property don't work for mutables. For now, we avoid that problem by assuming a change happened whenever a mutable property is set. change_hook_property is a bit untidy at the moment while I work out how to deal with mutables. As an example of using Bug.extra_strings to patch on some useful functionality, I've written becommands/tag.py. I'd suggest future add-ons (e.g. becommands/depend.py?) use the "<LABEL>:<value>" string format to keep it easy to sort out which strings belong to which add-ons. tag.py is still missing command line tag-removal and tag-searching for `be list'. Perhaps something like be list --extra-strings TAG:<your-tag>,TAG:<another-tag>,DEPEND:<bug-id> would be good, although it would requre escaping commas from the tags, or refusing to allow commas in the tags... libbe.properties.ValueCheckError also got a minor update so the printed error message makes sense when raised with allowed being an iterable (i.e. check_property) or a function (e.g. fn_checked_property). All of this digging around turned up a really buggy libbe.bugdir.MultipleBugMatches. Obviously I had never actually called it before :p. Should be fixed now. libbe.comment._set_comment_body has also been normalized to match the suggested change_hook interface: change_hook(self, old, new). Although, I'm not sure why it hadn't been causing obvious problems before, so maybe I'm misunderstanding something about that.
