version bump for next release. #15, v1.3.1
Fix two bugs for upgrade path
1) On clean install the "data needs update" message was shown instead of the "download all data on first launch" message
2) When you rotated on update, it would skip the process - the new version was being put into sharedpreferences too early
Moved logic of changing ViewPager pages into the ViewPager itself.
