added lots of stuff in this update, some of which may be a little green still.
- commands to navigate comment trees
- up to top-level comment
- prev/next same-level comment
- various commands to selectively fold (hide) comment branches
- un/fold current comment
- un/fold current comment + its children
- un/fold current comment's entire branch
- un/fold entire buffer
- added more sorting/listing drop-down widgets to make it easier to see what sorting is in effect (and to change sorting by mouse)
- fix tab navigation to (hopefully) all links everywhere
- make default sorting/listing in views better match the web UI
- fix sorting options in user view
- various other fixes
one thing to note is that this release switches the S/s bindings, for consistency.
