Translations reopened

[Wladimir J. van der Laan]

Oops, it appears that the transifex site was no longer accepting translations for bitcoin for some reason. I reopened it.

Note that the current bitcoin translation resource has been pointed at the 0.9.x tree. This means that any translation changes will be used in 0.9.x minor versions (next one to be 0.9.3).

I will add a new translation resource for 0.10.x, the next major release, cloned from the 0.9.x one, once the messages stabilize in the development tree.
