ui: Various amends for 1.7beta

[johncowen]

This PR is a set of slight fixes (both functional and visual) ready for 1.7beta. Mainly as a result of merging 2 feature branches (namespaces and discovery chain viz) together and then integrating them:

1. href-mut: only add a nspace if the routeName starts with dc. We know only dc-starting routes can have a nspace parameter, and this then rules out appending a nspace to the settings route.
2. aria-menu: Change direction to orientation to match the w3c aria documentation vocab.
3. use the same selector to select menuitems
4. Add namespaces to disco-chain work
5. Logging in with nspaces enabled will take you to the origin namespace for the token. There was no check to make sure namespaces where enabled or not before doing this. This adds the simplest fix, but will be further changed later down the line
6. Tweak position of tooltips for disco chain.
7. Slight menu padding tweaks.
8. Increase font size of our flash-messages slightly.
9. Keep namespace main nav menu in sync when creating a new namespace

There's potentially more to be added to the end of this but I'm PRing now to get 👀 on it as early as possible.

This is now ready for review, we don't envisage any more commits on the end of here.

P.S. Apart from figuring out why we are now failing our tests! Sorry for the noise! All good! 🎉
