Pebble: JS basic implementation of transaction acknowledgment

Browse Source 
JAVA side:
- first trivial handling of ACK/NACK message,
- fake the location age until an update mechanism is implemented,
- make the appmessage parsing more robust,
- comment the forecast mimicked reply as it was wrong and confusing for some watchfaces
