Code review comment for lp:~trb143/openlp/trans221

Actually... Just ran OpenLP with this branch and noticed an error... In af.ts (Africans?) English is just translated for the languages entry in the languages menu, this should be fixed.
Also a minor issue: We have 2 "English" entries, one for "en_GB", and one for "en". Should one be called "English (GB)" and the other "English (US)"?
Sorry about changing my mind...
