Title: Show busy on register to school server

School server registration can take a few seconds, depending on network
activity. Worst case is when there is no school server on an adhoc
network.

Show the shell is busy. A busy cursor does not work for touchscreens,
so an alert is used. This is in keeping with the alert already used
when a register to school server finishes.

Test case: connect to an adhoc network, then try to register. A busy
message will appear, then some time later a failure message will appear.
