[bug-idutils] idutils.el and Emacs 22

[Tom Tromey]

Emacs 22 comes with an updated compilation mode.  I've changed
idutils.el to work with it; new version appended.

Changes are:

* Uses define-compilation-mode
* Sets gid-mode-font-lock-keywords so that the initial "Gid started"
  message is not treated as a hit to find
* Uses compilation-start so that the hits are highlighted properly
  on next-error
* I didn't like how buffers were named after the search -- I just
  started using gid (what was I thinking all those years?  This is a
  great tool!) -- and I was surprised to find a lot of old *gid-FOO*
  buffers around
* Now uses thing-at-point

Anybody considered trying to get this code into Emacs rather than
shipping it in idutils?
