Status bar, more button cleanup

* New status bars for getting and sharing access, required a bunch of css changes to the roster
* Updated button styling (ask for access, start, offer access, grant, ignore, accept, and decline buttons are green, the rest are grey)
* New hamburger bar icon

Tested in UI and added new cases to ui.spec.ts
I guess my pint is that the 1 vs 2 vs more thing is reasonable in english, but doesn't actually work in all locales. The if / else loop here also breaks localization to some degree iirc
