Add galaxy role path which will be ignored by git

This change will ensure that local testing, with online roles installed
via galaxy, are not creating a dirty git tree. To build the separation
an empty directory "roles.galaxy" has been added which the galaxy command
will use to install external roles. All of the role path settings have
been updated to accomodate this new directory.
