Blynk fix for partitions 2-8, Push notifications for power/battery/alarm

[kricon]

Blynk examples now call pauseZones on partitions other than 1 #190. Viewing event buffer now also works fine on partitions 2-8.
Memory/Programming leds now also work on partition 2, doesn't work for partitions 3-8 for reason taligentx stated in #182
Added push notification for battery/power trouble/restore and partition in alarm (partition you've selected in blynk project) EDIT: committed sending push notification when alarm occurs on all partitions (with partition number on which alarm occured), not just the one selected in Blynk app.
Note that you must add widget:notification in your blynk project and enable notifications. Works fine when phone is locked and Blynk app isn't open.

It's possible to make tabs in Blynk project and for example have one tab only for controlling one partition, second tab for second partition, third tab just for controlling PGM's and viewing event buffer, and fourth for Blynk serial terminal where it can log latest events for example arming/disarming/alarm/zone low batteries and such. But that requires a lot of code addition, as printPanelStatus now only supports viewing past events from DSC buffer and displaying them on virtual LCD. Also, zone low battery push notification would be nice addition aswell, I'll see if I can implement it.

EDIT: Just noticed a bug while testing: if you press ( * ) from real keypad which is set on partition different than one on Blynk virtual keypad, it calls pauseZones but never call resetZones (until status for that partition changes). Bug doesn't happen if you're doing programming, as all other keypads gets disabled and afterwards zones open/partition ready status message call resetZones. Probable solution is to call pauseZones only if ( * ) is pressed from same partition as the one on which is virtual keypad set. FIXED in commit

Thank you! It's great to have the better multiple partition support and notifications.
