Ubuntu One storage synchronization daemon (syncdaemon) startup helper.
This script decides whether to start and connect syncdaemon.
* If you've never used Ubuntu One file sync, or if you've disabled
file sync via Ubuntu One control panel (or equivalently via setting
files_sync_enabled to False in the syncdaemon configuration file),
syncdaemon is not started, and nothing happens as a result of this
script being run.
* otherwise if syncdaemon is not already running it is started, and
local rescan is allowed to finish.
* if syncdaemon has never synced to the server, or if there are no
credentials for Ubuntu One in the keyring, nothing further happens.
* otherwise, syncdaemon is asked to connect.
