Adds styles for seantis.dir.contacts and seantis.dir.roadworks

For the styles to work seantis.dir.base 1.6.1 needs to be installed. With it I am able to kind of namespace all directory products, resulting in fewer css directives, while ensuring that they don't overwrite anything outside directories.

seantis.dir.events stays in a different file, because it is radically different from the other directories product. Same goes for the yet unstyled seantis.dir.facility.
