We should make some sort of language maintenance tool.
I notice that keeping all those language files up to date can be a b*tch.
When you add one new string, you need to manually go through all the language files and add one line.

All files have (read: should have) the same variables defined with a translation (or at least in english), so it should be not that hard to have a script run through them and add/edit/delete the specified variable.

I'm thinking of a cli script, included in the svn as dev tool.
