update_caps() can now do presence broadcasting.

As part of adding this feature:

    - fixed bug in update_caps() not assigning verstrings
    - fixed xep_0004 typo
    - can now use None as a roster key which will map to boundjid.bare
    - fixed using JID objects in disco node handlers
    - fixed failing test related to get_roster

Several of these bugs I've fixed before, so I either didn't push them
earlier, or I clobbered something when merging. *shrug*
