Title: Add support for headers in first level sublibs

The sub-libraries that reside in the first level subdirectories in the library git module can now have headers inside include/boost subdirectories. 'b2 headers' will now link those headers into the global tree.

This makes the hack for Boost.Numeric obsolete.
