Merge branch 'feature/qaction-menus'

Menus, a toolbar and a generated shortcut reference, built on converting
the action registry from a hash of callbacks to QActions. Along the way:
three default key bindings that had never fired, a shortcut dialog taller
than the screen, thread list columns that could not be resized, no visible
feedback that a tag action had landed, and a tags column so wide it was
unreadable.

Backlog items 3, 8, 9, 13 and 14 done; 11 partly.
