[TEMP] Revert "Active Notifications:"

This feature's notification listening code was more focused on working than security.
AND, it introduced a few conditions that would periodically cause devices to lockup for ~10 seconds.

I would rather see this fixed than revert it, but it needs ALOT of fixing.

This reverts commit a8388ed50a13c21033f05bffd800bad6935ed608.
