Bugzilla:Adding a CHECKEDIN state

We want to add another status for fixes that have been checked in but not yet deployed to test. We have previously used a flag "fixed_in_cvs" for this, but that makes reporting difficult. This wiki page documents my work in making this work against bugzilla 3.0 (3.2 will include https://bugzilla.mozilla.org/show_bug.cgi?id=101179).

Please add comments and criticisms at will - if there are problems with what I'm doing I'd like to know about them!
