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
We are looking into having text variable substitution in translated strings.  When we have that it shouldn't be too hard to just assign the first userName, second userName, and # of other users to variables and put them into strings.  I'm going to leave this in for now because I think it will be much more readable if you are sharing with more than ~3 users to just show the total number rather than a truncated list
