Remove buggy breadcrumbs

Honestly, if your Dashboard needs *breadcrumbs* to help your users navigate, you failed. Go back to the drawing board, and SIMPLIFY, SIMPLIFY, SIMPLIFY. On top of that, the current breadcrumbs as just annoyingly buggy - to the point I have to go every 2 or 3 hours and 'clear the cache' to reset it to a usable state. All it's doing is helping ruin my trust in the tool, as I've not *ever* used it to 'go back' or 'up a level'.
