Add support for 'bind-key S-Left' and 'bind-key S-Right'

[cschar]

The following works in my local tmux.conf but I think it isn't supported in pymux (or in prompt_toolkit?)

# Shift arrow to switch windows
bind-key -n S-Left  previous-window
bind-key -n S-Right next-window

Thank you @cclay for this feature request.
It was not yet supported in prompt_toolkit. Now it is: prompt-toolkit/python-prompt-toolkit@6c76f47

This pull request should do expose this functionality in Pymux: #54
I'll merge it after the next prompt_toolkit release.
