This change makes some quite mechanical changes for the remaining

extension pack items: message of the day, notes field, comment severity,

stopwatch, XML review UI, review together, and the ship-it ASCII art

extension. For the most part this is just trivial updates to imports and

dependencies, but there are a couple tiny actual code changes:

Some text type stuff and defining JS type classes in the XML review UI
Mark the ships as raw strings, and fix up the signature for the signal

  handler for the ASCII art extension.

Installed and activated each extension.
