RFE: Include all languages

[Vasja1986]

The original installer allows to pick several languages both for the interface as well as for spelling. The deb package seems to default to us. It would be great, if other options e.g. uk were available.

It is actually possible to change at runtime! You can do this to get french, for example.

wp -l fr

I'll leave this issue open, because there should be a way to make it permanent.
