Overhaul user profile UI

Our previous iteration is hitting some limitations as the power of
profiles on Matrix grows. For example, where do we put common rooms or
extra profile fields?

I re-arranged everything to group similar actions together - instead of
throwing it all into one big list. We basically trade vertical for
horizontal space, and gives us more headroom for extra fields when we
want to add more.
