The error messages that appear during the variety of failures need updating.  They are vague and not terribly helpful.

Examples:

1. When a firmware update fails it displays, "There was a problem installing this update.  Please try again or contact support."  

We should know much more about what went wrong.  In the failure I'm deliberately causing I'm switching off the wireless in my router midway through the firmware update.  Fab4 will know it lost connection to its network.  We can display this fact.  Things we will know:

* did it lose connection to WiFi?
* did signal strength dip sharply, causing poor data transfer?
* did it lose connection to the update server?

2. When trying to connect to a SqueezeCenter server but that connection fails, it displays, "Problem Conencting.  Could not connect SB Touch to <servername>."

Here we would know:

* Is the server still broadcasting on 3483 UDP?  If so, we can conclude it's still running, and it must be a problem with other ports.
* Can we connect via 3483 TCP or 9000 TCP?  If the UDP test is TRUE, and this is FALSE then we're dealing with a firewall or security software.
* If no ports are pingable, then the Server may have shut down or crashed.
