[boost] [conversion] Progress Report

We are very close to being able to go live with boostorg at GitHub. * Following the instructions at https://svn.boost.org/trac/boost/wiki/TryModBoost, the "master" branch seems ready to go. * A couple of libraries on the "develop" branch may still have end-of-line issues. If so, those should be resolved first thing in the morning. So please be patient one more day, and then we should be able to get to work using git and modular boost. --Beman
