Added checkbox "Skip Download"

[roberthudson]

As per Tridge's request to skip downloading of SITL binaries

#2518

(also adjusted tab order of controls)

[AppVeyorBot]

✅ Build MissionPlanner 1.0.2547 completed (commit 3587c57bbf by @roberthudson)

I've tested this and it works nicely. It looks like this:

if the SITL binary doesn't exist you get a popup saying that it failed to download

[roberthudson]

I wasn't sure where to put the checkbox.

Placing it to the right of "Wipe" would mean widening the control. That might have negative consequences on narrower screens.

Feel free to adjust as you see fit.

Instead of a checkbox, would it be better to simply skip downloading if the binary already exists?

Or is it important to download the latest version? How often do the binaries change?

Sorry for the questions, I'm new here :-)

they change whenever ArduPilot master changes, which is often several times in a day. We usually do want the latest build, but in the future we might like an option to download one of the stable builds.
