[boost] Boost.Format Library Maintenance

Currently the Boost.Format library is being maintained by the CMT. I would like to petition for that responsibility and lighten their case load further. I recently assumed maintenance for Boost.Uuid, and I have added Universal Windows Platform support to Boost.WinAPI and Boost.Predef so that folks will have an easier time making Windows Store compatible apps. I have also been working on a change that will add UWP support to Boost.Random and turn it into a header-only library, and expect to submit that in the next few days. I would like to shore up the CI environment for Boost.Format and groom the backlog in trac and on github, and get all the open issues resolved. Thanks for your consideration, Jim King
