CodePaster: Do better checking on hosts.

Do an initial connection check on the host
(once per host). Add utility function to
NetworkProtocol, displaying connection check
message box.
Move the 'Paste' handling into the PasteView
dialog, such that the checking happens there
and the dialog stays open if something fails.
