Black/whitelisting for special phrases

Allows to restrict the special phrases imported from the wiki.
Blacklist allows to exclude certain class/type combinations.
Whitelist allows to define an allowed subset of types for a class.
Adjust to your liking in settings/phrase_settings.php before running
the specialphrases script.
