Steve Howell 763782a6f0 Isolate stream_list.js's DOM manipulation when updating unread counts. ...

This refactoring basically splits off two functions from update_unread_counts(),
which then becomes a simple three-liner.

The function get_unread_counts() is extracted, and it's purely functional
computation.  It paves the way for a more pull-based approach to getting "unread"
counts, where other parts of the program can just call it to get values as
needed without worrying about side effects.  It is staying in zephyr.js for
now.

The other function is stream_list.update_dom_with_unread_counts(), which
has a new home in stream_list.js.  It handles all the DOM manipulation
aspect of unread counts in the left pane, mostly by delegating to smaller
functions within stream_list.  Some of those smaller functions can now
be turned into private methods FWIW, but I'm not sure it's worth the
trouble.
