Refs #415 - incorrectly typed usernames not highlighted

It works for twitter, because tweets contain a list with referenced
(and thus recognised) users. This information is not available for
identi.ca, so there misspelled user names are still highlighted.

Closes #445 - preferences window now showing for statusnet accounts

This is probably more a workaround than a real fix.

For statusnet accounts, the preferences window crashed because
prefs.filter_nsfw_media was undefined. I don't know why.
I now just skip the code that uses this property when the
property is not defined.
