Merge pull request #76 from bkensey/dev-gradle-1.8-update

Update gradle wrapper to v1.8
Merge pull request #75 from bkensey/dev-spinner-breadcrumbs

I still think there's room for improvement, but for the sake of progress let's go ahead and merge this.
Tweak breadrumb spinner layout
Includes spacing and resource cleanup, and now transitions properly between the different text sizes set for portrait and landscape.
Implement a breadcrumb pager
This will better communicate the relationship between breadcrumbs and navigationFragments by visually tying them together through motion
Fix breadcrumb/navFragment pairing
Fixes a bug where if the fragment loaded first, the related breadcrumb would not be associated and initialized.  Now it doesn't matter whether breadcrumb or navigationFragment loads first.
Bump alpha version number
