Change from bjam to b2
Add [search-root] initial option, taking care that it works for relative or absolute paths.
Fix a couple of "initial_path()" cases that should be "search_root_path()" to fix a search-root-path option bug.
Remove -cvs option. file and directory names that begin with a '.' are now ignored, such as the .git file present in initialized submodule directories of a super-project.
Return 0 if no errors, 1 if errors. Also fix message still referring to CVS!
Minor message cleanups
Merge branch 'develop'
