Changes for a more flexible Component

[jakubikan]

In order to generalize this component to have it more flexible I made some changes.

I removed the filters (for index and loading) and the Breadcrumb Classes.

Other then that I changed the breadcrumb behavior a bit so you need to define a breadCrumb object in order to have a breadcrumb at this route. (if nothing is defined it will not show anything)

I also added the routeHierarchy to the block of the bread-crumbs component, so you can check inside the block whether its the last/first routeObject.

I hope that's in your favor.

I merged every thing and also, the test should also pass now also with the new code styling validations

This breaks backwards compatibility in multiple places. Interesting idea around index segments. I'll keep this open for now...
