Conforming to the Romanian team's decision to use trunk for the European routes:

I decided is time to change the tagging for the DN6 section that still used primary: București-Alexandria-Caracal-Craiova. All those changes ended up not having a comment because Potlatch ended up being stuck in a "saving" state and not coming out of it.

I know I should send a report, but I suspect I am not the only one seeing the problem, so I am not doing to do this unless is not fixed in a week or two.
