Add mwparserfromhell as dependency
Add mwparserfromhell as dependency

Even though mwparserfromhell is technically optional,
having mwpfh as dependency will make sure people who
setup.py install pywikibot will have it installed.

People using pwb.py are not affected by this, although we
should probably add a warning at some point.
