This commit is to back port a fix from 0.3.3 dev branch to the trunk. The directory provider will now use the boost::filesystem::is_directory function to determine if the passed in source is a directory. This allows a python client (through VFS::addNewSource) to add a directory source that is either an absolute path or a relative path from where the application is launched. [t:544]
