[boost] [filesystem] "." directory-placeholder added

An updated version of Boost.Filesystem has been added to CVS. The primary 
change is adding "." as a directory-placeholder to the generic path 
grammar.

This solves the problem of distinguishing between an empty path and one 
that acts as a placeholder.

This change does change some existing behavior: path("foo/..") used to get 
converted to an empty path. Now it gets converted to a path of ".", and 
thus the change will break any existing code which depended on the prior 
behavior.
