Messages with links in it must be parsed

Otherwise something like
"There is [/wiki/File:Amphoe_Sukhothai.svg another file] already on the
wiki with the same filename"
is returned and shown as such to the user.

C.f. http://www.mediawiki.org/wiki/RL/DM#mediaWiki.message

Also using title as reported by API instead of title that was entered by
user because the user possibly knows what they were entering but the
file that exists under a normalized name may be unknown but interesting
to the user.

Set message and group used on [[Special:SpecialPages]]

for [[Special:Campaigns]]. Currently it is listed under "Other special
pages" as "&lt;campaigns&gt;" (double-escaped), which looks weird.

Also the use of "Special:Campaigns" might be worth re-considering as
there will be possibly more campaigns, not only upload campaigns. But
this is not addressed by this patch.
