Add a web interface

[benjamingorman]

The web interface should display a list of the KAG servers connected, as well as some diagnostic information about them such as:

• Connected status
• How the long the TCPR connection has been active for
• Number of players connected
• Time of last TCPR line received
• Recent history of lines received

If the web interface worked using WebSockets, then as TCPR lines were received they could be sent instantaneously to the web interface. This would allow a user to see in real time what was happening over the connection, which could be very useful.

There could also be a feature for users to manually enter AngelScript commands to be sent to the servers.
