(bug 57698) recentchanges displaying raw topic title(?)

As part of an i18n message, topic titles (for which we don't allow wikitext)
were being parsed.
I'm tossing them in as raw parameter now, to make sure they're only replaced
after parsing (and manually apply htmlentities to make sure no unwanted html
shows up)
