Haiku R1/beta1 is finally actually really close now

At last, R1/beta1 is nearly upon us. Only two non-"task" issues remain in the beta1 milestone, and I have prototype solutions for both. The buildbot and other major services have been rehabilitated and will need only minor tweaking to handle the new branch, and mmlr has been massaging the HaikuPorter buildmaster so that it, too, can handle the new branch, though that work is not quite finished yet.So essentially all that stands between us and the release itself is a lot of testing, and more testing, and polishing all the little bits and pieces we've neglected along the way. I've already begun drafting the release notes, and the i18n translation tools have been synchronized with master, so even though the string freeze hasn't happened yet, the bulk of the translation work can begin.

I'm excited.
