Added keyboard shortcut for opening a tab from the corral.
Use shift and unshift so corral order is reversed.
Added changes to change log.
Added sorting of the closed tabs before rendering.

This way the sorting will work right away without any update method.  This can also be a foundation for user-selectable sorting methods later on.
Merge branch 'refs/heads/keyboard-shortcut'
Increased version to 1.2.
