Feature requests: Device sync and track share

[marcusbrutus]

Hi, very excellent application.

Only misses two features:

1. Device sync = synchronise tracks between all my Android devices.
(Or at least be able to keep common data in a Dropbox?)
An example of this feature is in the app Deliveries https://play.google.com/store/apps/deta ... deliveries

2. Track share = share a track with another email address,
so that they can add to their copy of TrackChecker.

Thanks and
Regards,

Marcus.
