app_terminal.py:  You can now set `"dtach": false` in any Terminal "command" section to disable (or enable) dtach support on a per-command basis.
core/server.py:  Added a more user-friendly error message when creating the SSL directory fails.
Bookmarks plugin:  Fixed a bug where--if you had corrupted bookmarks with missing names--you couldn't delete them *or* edit them *or* fix.  Now such bookmarks will have their name automatically corrected using the bookmark object's URL.  Also, bookmarks with a missing URL will be removed completely and will no longer persist in localStorage as artifacts.
