Fix #117: Card tags now match disregarding case and punctuation.
Merge remote-tracking branch 'upstream/master' into case-insensitive-card-tag
Ignore diacritics as well.

So [card]jotun grunt[/card] works as well as [card]Jötun Grunt[/card].
Also I removed some debugging information I accidentally left in.
Merge pull request #197 from arxanas/case-insensitive-card-tag
