[Xfce-i18n] catfish.pot

[scootergrisen]

Just got email that catfish.pot was added on 
https://www.transifex.com/xfce/xfce-apps/catfishpot/

But its already translated on 
https://translations.launchpad.net/catfish-search

Only seem to be 3 extra strings added.

Maybe inform people about this so they dont have to translate 109 
strings that might already be translated elsewhere.

Maybe change catfish.pot to Catfish.
