Minor tweaks to Smart Alarm

A few updates you may wish to consider:

* Changed to Safety & Security group
* Used Green "HAL" icon
* Use sendNotificationEvent on PanelStatus instead of Push/SMS (use those for alerts only)
* Simplified the PanelStatus message to minimize wrapping caused by location.name

I didn't like getting the long SMS and Push messages every time the alarm changed state - once it is all working, simply updating the Hello Home log seems to be enough.  Also, for some reason the sendPush() and sendSMS() msg is displaying on (what appears to be) 16 lines when only 8 zones are being used; the other lines appear as blank lines. Changing to sendNotificationEvent() somehow fixes this too.

The other changes are cosmetic, but for your consideration.
