Title: Add ground elevation parameter

I've added the ```DZ_Elev``` configuration parameter in order to simplify alarm setting. I found myself constantly doing the math to convert AGL alarm elevations to MSL elevations for the configuration file. The new parameter will allow users to enter the DZ elevation once and enter alarm elevations separately as an AGL value.
