[FIX] base, account: usability on company currency selection.

We now display all the existing currencies (even the unactivated) instead of a link to activate more of them, and upon the save we make sure to activate the selected currency if it's not yet the case. That's better from a point of view since it avoids jumping off of the screen then come back to make this setting
