Breadcrumb logic

[kstapelfeldt]

The relationships represented in the metadata panel beneath an object will form the representation in the breadcrumbs. Where there are additional compound relationships between the current location of the object and "Home," this will be represented by an ellipsis (...) - see attached screenshot

In this way, we are moving away from the path-based breadcrumb (which is less popular online) and creating a location based breadcrumb that uses similar visual cues to those utilized in attribute-based breadcrumbs.

All part of and member of relationships should be represented in the breadcrumb.

This is complete and tested, but is being reviewed for translation branch. @Natkeeran to review: https://github.com/digitalutsc/islandora_breadcrumbs/tree/breadcrumb-translation
