Gaia GPS iOS v10.4.1

This update addresses bugs in the major 10.4 release (see 10.4 release notes).

• Images exported by zip and email now have filenames based on date-time, and are unqiue.
• Fixed a crash after stopping recording on iPad.
• Fixed issue with grid labels being under toolbar, or not showing at all.
• Fixed some map sources not staying removed on app restart.
• Saved menu on iPad GaiaPro did not have an option so view Areas, and now it does.
• Fixed a crash when toggling automatic publishing of tracks.
• Fixed a crash when using Airplay with the zoom label turned on.
• Fixed airplay not activating properly when launching the app, when already connected to an external display.
• The left menu was distorted under iOS 7. It looks much better now.
