Add a tui for ticket

This commit sets up a basic tui for the current functionality. It's
traversable by keyboard and by mouse and shows the ticket state via tab,
info in a row, and the description in it's own box when selected. This
is necessary for a good user experience for in repo tools. Files are
fine, but interactivity is better.
