General Update

Well I managed to move all development back to svn.boost.org. The experiment with mixing multiple repositories wasn't particularly nice, since cross-repo merging just isn't supported by SVN (or, for that matter svnmerge.py). But, I have an intact history now so development can continue. Current work is being done 'blind' though (ie. without a compiler) so expect branch work to be particularly unstable. I am trying to keep the trunk stable but again, for the few days at least, that may have obvious issues.
