Subject: [PATCH] Try to handle Android Rescue Party triggers.

The Rescue Party trigger manifests itself when a user is trying to boot
a ROM but keeps getting dumped back to recovery.

Normally, TWRP doesn't capture this, and the user is often wondering
what is happening. This patch captures the trigger and presents a clear
message to the user about what is going on (with options of how to
resolve the situation).
