main: treat elevation offset as offset from horizon

Browse Source 
Rather than having somewhat confusing flipped logic when the rotator is
operating in the 180-90 degree elevation regime, this internally
performs sign flipping. This means that a 3 degree elevation offset
means "point an additional 3 degrees up from the horizon" regardless
of whether the rotator is operating in the 0-90 or 180-90 elevation
ranges.
