strange language in the status pages

[Tino Meinen <a t meinen chello nl>]

Browsing through the status pages (we have 100 languages now!) I found a
strange language that I haven't heard of before: nl-1
It's at number 87 right now.
Looking closer I see that there's only one module translated, and it's
an old version of a gucharmap module translated to Dutch (nl) 

I've no idea how that language ended up in the status pages, but I think
it can be savely removed (bringing the number of languages back to 99)
