Add script to start the current build.

Start moneychanger-qt, including correct setting of LD_LIBRARY_PATH to
include the shared library for qjsonroc.
Update names also on start.

Update names also directly after start, not just when the first 10
minute timer fires.
Fix name status display during name_update.

During a yet unconfirmed name_update transaction for the registration of
names, display also 'pending' instead of 'invalid'.  Catch exceptions
that may be thrown during the status retrieval.
