NHMON - Networked Host Monitor / News: Recent posts

Added an option to add a textual note for a host (in the config
file), as well as a dialog to add/update it at run time.
This feature may be useful to use in conjunction with "ignore"
option to remind about the reason for ignoring the host (e.g. the
host has no hard drive).

Added "Shell" button to pop up an Xterm with a shell on the remote host.
Added signal handling.
Rewritten thread shutdown synchronization.

The first public release of the package is here.
