More intelligent committe function translations

[Jelmer van der Linde]

Currently combined functions (as used by the WebCie and FotoCie) are translated as a single string. Of course, that does not work.

We should split functions on comma or slashes and then try to translate each function separately using the double underscore function.

(To enlarge the vocabulary of translations we could add some more predefined functions to that method that supplies these function names to the admin in actieveleden.php)

[Jelmer van der Linde]

Translate and sort committee functions that consist of multiple functions correctly. This fixes issue #14.
