FlightPlane >> Save WP File discards some accuracy of points

[rmackay9]

It seems the "Save WP File" button on the Flight Plan screen saves the waypoints to 6 decimal points instead of the full accuracy of the points (usually 7 decimal points). This is the way to re-create the problem:

1. open MP and connect to a flight controller
2. go to the Flight Plan screen and enter a mission by clicking on a few places on the map
3. note the lat/lon of the waypoints displayed in the command list at the bottom
4. press the Save WP File button to save the waypoints to a file
5. open the file in a text editor and compare the lat/lon values to those shown on the MP's flight plan screen.

In my tests, at step 5 the values are slightly different as shown below:
