* 16/Nov/2004: version 0.2.0 Release notes:

This is a "major" release, with more than 1,000 lines of new code plus a lot
of changes, especially in the download threads. There is a new format for a 
couple of Dbs , so the first time the program is run, the Dbs are migrated. 
This operation can be lengthy, so please be patient. If you can, backup the 
"klibido/db/" dir before starting the program. 

What's new/changed:
 - "Persistent" download queue: KLibido now saves the progress of download 
   and, in the event of a crash/restart/whatever, asks you to resume it.
 - Added the shortcut manager and some default shortcuts (note that CTRL-W
   closes the active tab)
 - Double clicking on a header views it
 - Added group categories and group aliases. This is only a matter of how
   groups are displayed in the grouplist, but should help people with a lot
   of subscribed groups. Use the "group properties" menu to add categories. 
 - Queue balancing: if you have more than one server subscribed, KLibido tries
   to balance the load across the servers, BUT ONLY IF THEY HAVE THE SAME PRIORITY.
   This should accomodate the needs of people with bandwidth-limited servers as
   well as the needs of people with bytes-limited servers.
   NOTE: this works only with articles whose headers are downloaded after the 
   Db update
 - KLibido should now gracefully handle write errors, including out-of-space 
   errors: newsgroup updates fail with an "I/O error", while post downloads 
   are kept in the queue AND the queue is paused. This seems a reasonable
   behavior to me, but I'm accepting comments :).
 - Lots of minor changes and bugfixes (see ChangeLog)
