Extract sport field from GPX

[slackline]

Many GPX files will record the activity type directly in the metadata. For example OpenTracks records this in two places as both <type></type> and <opentracks:typeTranslated></opentracks:typeTranslated>...

It would be useful if these could be extracted when loading and mapped to the sport field which is required when uploading a track to fittrackee as it would allow batches of GPX tracks to be uploaded automatically without the need to manually add the sport field when doing so as is currently required.
