#12 Add additional connection status to gui

[Ian Sheldon]

The following patch adds additional status information
to the web gui.

It tells you why the connection is dropping, and gives
a quick and easy way to determine if the connection is
about to die, i.e., if we don't receive packets from a
host then it will indicate this.

It does this by using a single character at the start
of the client name (in a manner similar to cdparanoia).
So, + indicates positive connection, whereas an
exclamation mark indicates the connection is likely to
die soon.

Connection status is also indicated when connecting to
new hosts, e.g., ``[ConnectTimeout]''.

It does this by overloading the client name field which
is not especially elegant, but works quite well.

Patch works against CVS and not the 0.4.3 tarball.
