[et-mgmt-tools] [PATCH] For connection errors, show full details

[Richard W.M. Jones]

Currently virt-manager hides the real details behind a connection 
failure in a log file, which users have to "just know" how to find.

This patch adds a new dialog class, vmmErrorDialog, derived from 
gtk.MessageDialog, which has a "Show details" button to show the true 
reason for a failure.  It modifies the exception handler for connections 
to give the underlying reason and a stack trace.

Also attached, two screenshots so you can see what I mean without 
needing to apply the patch.

Rich.
