language selection persistence

[jganseman]

In an english-language browser at least: when going to http://be-oi.be and selecting a language; on the next page (selecting the contest), that language choice is not kept in the redirecting links to either beoi.be-oi.be or becp.be-oi.be (i.e. on these websites the language selection pops up again).

Not sure if there is an easy way to append '/nl' or '/fr' to the links in source/localizable/index.html.
Perhaps storing the choice in the browser cache could be a quick fix, for recent browsers at least?
