General:
- Started documenting Catalog Pruning and Recycling.
  Added catmaintenance.html and recycling.html

Changes submitted this submission:
- Fixed the query command bug.
- Implemented PID files to prevent two copies of Bacula
  from running at the same time. Be sure you --with-pid-dir
  points to a working directory.
- Modified ASSERT() to cause a segmentation violation. This
  permits a core dump.
- Worked on gnome-console. It paints better, it tells you if it
  is ready to accept a command or processing one, and it is
  almost entirely GTK+ (rather than GNOME, I'm removing GNOME
  a bit at a time).
- Limit to 100 the number of tape labeling errors in a single Job.
- Add some additional ASSERT()s to the database routines. I don't
  like ASSERTs but they do catch bugs.
- Tested and debugged recycling of Volumes.  Needed to change
  the Director-SD protocol slightly.
- Removed the experimental SIGHUP in the Director as it is a
  potential source of errors.
- Added Level, Pool, Messages, and Storage keyword/value scanning
  to the Schedule Run record.
- Improved printing of Schedule resources with "show schedules"
- Do not autoprune Jobs/Files if the Job errs.
- Updated newvol() to pass back the updated Media record.   
- Fixed the "update pool" command, which was broken during a much
  earlier code reorganization.
- Improved a few of the pruning messages.
- Removed readline inclusions from gnome-console (hang over from console).
- Make Jmsg use daemon message handler if no message handler is defined.
  This is always the case in the SD and FD.
- Started removing __PROTO(). With C++ prototypes are manditory, so why
  keep around legacy code.
- Added a good deal of message internationalization -- more to be done.
