[tmux integration] Store "none" for the tab color when tab color is off for a session. This fixes a bug where new tmux sessions didn't use the profile's color. Uninitialized (which is now indicated as an unset tab color) should (and now does) mean to use the profile's value. "none" means no color. Otherwise it'll be a #hex value.

Tiny typo fix

Draw tab color in white if the window appearance is dark. This happens to work for the main menu (it has a window!) as well as the context menu on a tab. Issue 6286.

Don't crash when you delete a password manager entry that is your only one and you are editing the password

Remove mechanism for catching proc_pidinfo and statfs timeouts. It was causing crashes, but I don't understand why. Perhaps mixing ARC and non-ARC code has some problem? I saw lots of crashes on 3.1.4 where proc_pidinfo exceeded the timeout and when it finally returned there was heap corruption. It looked as though the dispatch group had been freed even though there was an outstanding reference to it. At any rate, if proc_pidinfo is hanging you're going to have a bad time even without this workaround.

Avoid looking up a negative index when you have a tail find going (i.e., the find panel is open) and you clear the buffer and it becomes empty (i.e., there's nothing before the cursor such as a prompt at the time you do cmd-k). Issue 6271

Remove incorrect tooltip on "show mark" button in prefs.

Having merged in the PR for selecting an account after opening the password manager from a trigger, add manual retain-release code and rename ivar.

Fix a bug where double-tap shift to open a hotkey window didn't work. It was using the mask for capslock instead. Issue 6251
