Alexandre Lissy 1903e36586 Bug 1100876 - Add showOnlyOnce to MozBehavior dict. r=mhenretty, r=smaug
There are some notifications that we know we don't want to resend. For
instance, Voicemail notifications are some, since everytime the network
will be ready it will notify us of the status, so we don't have to
resend it on reboot. We add a 'showOnlyOnce' key in the MozBehavior dict
for this usecase.
