[boost] [range] Merging algorithms into release branch and <boost/detail/algorithm.hpp>

The release branch's version of <boost/detail/algorithm.hpp> contains several range versions of STL algorithms that duplicate those in the new version of Boost.Range. The trunk version has removed these duplicate algorithms (in r60919), using Boost.Range instead. This note is to inform whoever merges the algorithms in Boost.Range into the release branch to merge r60919 as well to avoid duplicate function errors. -- Jeremiah Willcock
