Fixed a problem with the audit runs getting stuck
Various changes

* Some minor changes to character creation, including allowing the use
of spaces in the character name.

* Created a 'Protected' class in anticipation of using them to identify
which instances should not be cleared.  (Characters, for example, will
be 'Protected')

* Brightened the 'Exits' line color.

* Added slow 'press enter to continue' output to the PromptState class.

* Created a 'News' channel which will, among other things, announce the
arrival of new characters into the world.
