Title: Macro to remove filesystem dependency

This patch adds the BOOST_SPIRIT_X3_NO_FILESYSTEM macro which removes the dependency on boost filesystem when enabled.

There is only one line in X3 that depends on filesystem, so I think that it is a good feature to let the user disable it if it doesn't want the dependency.
