Export route as gpx

Should have the option to download a route so it can be used on a sat nav

Hey, I'd like to work on this issue.

@jspaine, are you available to help with this for questions and reviewing a pull request? I am not at all familiar with the route mapping funcionality and won't have the time in the next few weeks to look it over and understand how it works.

Hi, you're welcome to do it, I think most of the other issues are higher priority though.

[ShelleySuhling]

All other issues seem to have other people working on them. Could I get more context regarding this issue?

Well #314 hasn't had any activity since November, so it should be safe to work on.

The idea with this was that if you could export the route as a file that could be loaded into a sat nav, you could give it to delivery drivers to help deliver the packages.
