A Review Board Extension that allows modification to the
default "Ship-It!" message when publishing a review via
the "Ship It!" button.

The modifications to original "Ship-It!" text can be anything,
as demonstrated by the ship ascii art currently included by
the extension.

TODO:
- To set up the configurable page
- Move the files out of /reviewboard/ to the appropriate
  extensions folder
- Trim out unnecessary stuff
- Possibly allow ascii art to be defined elsewhere?

(Note that while this is still WIP - you can download the diff
 and apply it to try it out!)

Manually tested with different ascii art patterns
