Update Home Alarm Device Type

Introduces two new features:
Adds a "lock" capability that allows SmartApps to "lock" your HomeAlarm arming it in Away Mode.  So you use "switch" to arm in "Stay" mode and "lock" to arm in "Away" mode.

Also added an "AD2Pi Config" tile.  This allows you to send a "C" command to the AD2Pi to request it to report back the AD2Pi device address which can be viewed in the message tile

This tile will also append any command that has been input into the AD2Pi Configuration Command preferences.  For example to change the AD2Pi address to 31, do the following:
Open the "Preferences" tile
Enter "ADDRESS=31" into the "AD2Pi Command Configuration" field
Hit "done"
Press the "AD2Pi Config" tile which will send over the command "CADDRESS=31"
The AD2Pi will respond with ADDRESS=31

Thanks to Sean at AlarmDecoder for the tech support to make this fix possible.
