Survey (Grid) Imperial Support, + random clean-up. Issue: #541

@meee1 I think I got it(git usage) right this time.

Still have to set altitude in meters, although it will add WP's in feet.
Issue: #541 addressed.

Tristan, I use imperial but after using the latest beta I am finding the mix of units confusing. Altitude is still in meters, while resolution is in cm. Most people who use Imperial do so because in aviation the international ICAO standard is in feet (eg 400ft limit). On the other hand, ground resolution is almost always referred to in cm. Here are some possible solutions:

1. Always display both units, at least for key values like I named above, or
2. Include a toggle switch inside the Survey tool so we can switch back and forth quickly as needed.
   I'm usually adjusting my grid to get to a target resolution in cm/pixel.

@tristannovak,
Also, in Imperial mode, the "Distance between images" shows as feet, but the CAM_TRIGG_DIST parameter requires meters. It would really be helpful to have an instant toggle switch in the lower "stats" pane to display either type of unit.
Is there a way I can contact you more directly? Perhaps a username for DIYDrones of RCGroups so I can PM you? I'm iskess everywhere including hotmail.com

@tristannovak Nice work here! I agree with @iskess - I was just unconfident enough in what units where what that I just did everything in meters. The altitude is the biggest issue in my mind.
