#8 Server timeout might not signal to user.

[JukkaJ]

If the server times out the connection to the client, the viewer doesn't notify the user in any way.

This has been reproduced in at least two different ways:

1) When as a user in the world, select several items (500 or more) in edit mode and delete them all pressing Del key, or from Edit->Delete. The server log will start a lengthy output of all the items being deleted. While this happens, the user cannot move in the world. Eventually, the server disconnects the client and outputs something along the following in the log:

The user doesn't get a notification of this happening, but will stay indefinitely in the world, unable to move.

Reproducibility: 2/2

2) When connected to the world, delete the server process OpenSim.exe forcifully using the task manager.

The user avatar cannot be moved in the world afterwards, and even after an indefinite period of waiting the user will not get a notification of being disconnected.

Reproducibility: 1/1

Expected (both cases): The user gets a notification of the connection having timed out and is returned to the main connection dialog.

Tested on server version 20080911 and client version 20080915.
