FileIO integration

[alhirzel]

Have you considered integrating with FileIO? It might be as simple as this (and adding the FileIO-style load and save methods) after registering GPX.jl:

add_format(format"GPX", (), ".gpx")
add_loader(format"GPX", :GPX)
add_saver(format"GPX", :GPX)

Good idea @alhirzel
PR are welcome

Have you considered registering GPX.jl according to this? https://github.com/JuliaRegistries/Registrator.jl/blob/master/README.md I think as the owner you may need to do this?

I'll work to add the FileIO stuff
