highlight "Format recommendations" and "Standards Watchtower" in some nice way

We have a lot of items in the menu now, and it's not clear any longer that these are the two fundamental parts of the SIS. I hope that Eliza can find some nifty way of highlighting these two cells :-)

Meeting decision: Eliza is going to think of a nifty way to do that.

Meeting decision: the current sub-root "Centres" is going back under "Format recommendations", to make the division into the Recommendations part and the Watchtower part clearer.
