v0.3.0

Added

• Every shortcut can be changed: the window's own (new tab, next and
  previous tab, clipboard, text size, Preferences) join bunk's pane keys
  under [keys]. Preferences > Keyboard records a new shortcut when you
  click one and press the keys, and asks before taking a key another
  action uses. A key set for two actions is shown in a banner.
• bunker config set, get, and list change and read any setting from a
  shell, with the same checks as Preferences. GTK's key spelling
  (<Control>Right) is accepted.
• The cursor blinks. [cursor] blink is system (the desktop setting, or
  what the program asks for), on, or off, as in Ptyxis.
