UN Job List: Improved navigation

Lately I have  been working on the UN Job List a bit. Most of it was behind the scenes but there are some visible changes in particular on the left-hand navigation of the UN Job List. The improvements were derived from the feedback I received via the UN Job List survey, the feedback via comments and then also some plain statistics checking for the most popular pages on the UN Job List.
If you have further ideas, fire away in the comments below. In particular I’m interested in how you like the new structure of the left-hand navigation menu.
