look: move language selector to RHS, don't use country flags

The language selection being a flag never sat right wight me:

 1. Its positioning next to 'CEBULACAMP' implied more that it's a
    cebula.camp logo or intrinsic flag of the event or something.
 2. I think it's the first site I've ever seen that has a language
    selector on the left hand side of the navigation bar.
 3. Using country flags as language icons is wrong [1].

[1] - just ask the Swiss or the Belgians.
