part of PR #1109 - data.base entries

Part of the pull request by entrez, changing a few data.base entries
recently introduced by PR #1108.

Changes ice box to a different quote, but I've re-applied the prior
quote to ice terrain rather than delete it.  Also replace a UTF
apropostophe in the ice quote which escaped the previous purge of
such things.

Replaces the C.S.Lewis quote for Demonbane with a one-liner from the
Bible.  I realized a bit late that Demonbane is no longer a sword and
never given to lawful Angels as starting gear anymore, consequently
the new quote doesn't fit very well.

The PR changed the helm of brilliance entry to be for all helms and
this rejects that.  Instead, it adds a few generic helmet descriptions
and changes the helm of brilliance quote--now misquote--to be useful
to players, describing it as crystal rather than steel.

Pull request 1109 is still open--there's a second commit in it dealing
with fruit name handling that this commit doesn't touch.
