[aprssig] Proportional Pathing User Interface

[Robert Bruninga]

This would be my USER interface for setting
up a mobile:

15 sec path*:  none     (means none transmitted)
30 sec path*:  none      
 1 min  Path*:  DIRECT   (transmitted but no path)
 2 min  Path:    WIDE1-1  (might be RELAY in Europe)
 4 min  Path:    WIDE1-1,WIDE2-1
 8 min  Path:    WIDE1-1,WIDE2-2
16 min Path:    none                    (default)
32 min Path:    none                    (default)

Decay   when stopped    ON       (default)

With these, the user can do just about anything.
from fixed rate to Proportional Pathing.   If the
user sets anything other than direct in the first
three, he gets a QRM-ARE-YOU-SURE WARNING.
