[Feature Request] Ability to use a different configuration depending on location

[tmiw]

I was resetting my FreeDV configuration back to my "home" setup (Hermes Lite 2 SDR via a virtual sound card) after operating portable this past weekend and realized that this would be something that might be useful for others as well. Figured I'd put it here as a TODO for me (or someone else) to get to eventually. :)

Anyway, here's what I'm thinking so far. Feel free to update as needed.

Configuration options that should be updated on a per-location basis:

• Sound card configuration
• PTT configuration
• PSK Reporter grid square
• Regular text field (if PSK Reporter not used)

Configuration options that should remain the same regardless of location:

• PSK Reporter callsign (?)
• Audio filters
• All remaining options in Tools->Options.
