Doc Bug: Mission · QGroundControl Developers Guide

[hamishwillee]

https://docs.qgroundcontrol.com/en/releases/daily_build_new_features.html#plan-files states

Previous version of QGC saved missions, geo-fences and rally points in separate files (.mission, .fence, .rally). QGC now save all information related to a flight plan into a single file called a Plan File with a file extension of .plan.

Upshot is that we have to update the file formats described in pages including Mission · QGroundControl Developers Guide

@DonLakeFlyer Can we have doc for new file format. How do you want to deal with the old doc formats - do those docs need to be archived or can they just disappear?
