mozilla/tools/buildbotcustom and mozilla/tools/buildbot moving to Mercurial

The time has finally come for these two CVS modules to get a better home. Here's what I'm proposing:

1. Early next week I will import these modules (with history) into http://hg.mozilla.org/build/buildbotcustom and http://hg.mozilla.org/build/buildbot.
2. On Friday, January 30th, 2009 I will delete mozilla/tools/buildbot and mozilla/tools/buildbotcustom from CVS and put in READMEs pointing to their new homes. I don't believe there is any reason to keep them around once the new repositories are live. They will only serve to cause confusion.

Moving these will be a change for the better, I believe. It will let us import new versions of Buildbot without the hassle of CVS and in the case of buildbotcustom, let others work on it more easily.

If anyone has objections to this plan please respond to this mozilla.dev.builds post. If I don't hear anything by Tuesday, January 27th I will proceed with this.
