Dutch translation

Over the last week I translated the WeUseCoins website to Dutch in the hope this would make it easier from some Dutch speaking people to get involved in the Bitcoin community. 

I tried to keep the Dutch version as close to the English one as possible. Not sure about the word "wallet" in Dutch though. I went with "portefeuille" but "portemonnee" is also used, it depends on what Dutch speaking region you come from I guess.

Alle pages have been translated but the images are still in English. Are the original images available somewhere or are there any plans to convert these to SVGs?

I hope this is a useful change, if not, feel free to make some remarks.
