Added detection and partial decoding of Opel Mokka car keys.

Presumably a transponder of type "HITAG AES 4A NCF29A1M", so it might very well pick up other compatible brands as well.

Only extracts key id and event type. There's no decryption of payload.

Do you have a sample signal file for this decoder? @vidarino

…erbanan#3305)

Add support for decoding a 2GIG-branded Tilt Sensor that uses the Honeywell protocol (as identified by signal characteristics and/or FCC documentation). The sensor broadcasts unique payloads when tilted or restored to horizontal.

Sure!

Here are one of each signal type from two of my key fobs. (Apologies for some cruft in the files.)
