- Fixed bug when reloading the config file which had the side effect
  of basically merging the old list of hosts to ping, with the new
  configuration.
- Fixed a few problems when using TermReadKey > 2.19. The problem
  showed itself by Pingmon not being able to respond to keypresses.
  The recommended minimum version of TermReadKey is 2.20
- Added support for signals.

  SIGTERM, SIGQUIT, SIGABRT - Quits Pingmon
  SIGHUP  - Reloads configuration

  The success of these signals, largely depend on the operating system
  you are using. Tested with Linux (RH9) and Solaris 9.

- Pingmon no longer stores the total number of hosts down since it was
  started, it only stores the total per scan which makes more sense.
- Removed the "Zero Downed Hosts" option as this no longer makes sense.
- Pingmon now maintains a list of hosts which are currently down. This 
  can be viewed by pressing "d".
- Small fixes to the SPEC file for RPM installations.

---

- First public version
  (Pingmon was originally intended to be for internal use only)
- Moved to using Net::Ping instead of the operating system's ping command
- Added support for using TCP and UDP pings as well as ICMP, thanks to
  Net::Ping
- Removed support for sending specific numbers of packets to each host.
  Was a fairly useless feature anyway.
- If a host goes down it now displays (L) if its been logged
  and (-) if it hasn't
- Few minor changes to the display for better space utilisation
