Attempted to move section over to the section-specific new breadcrumbs function.

Browse Source 
I think the problem is, the index context needs to be a higher priority than the new context element, but when referencing data with `{.}` the new context element needs to take priority. I could either combine entries in the context tree so that variables like $idx and $len live side-by-side with real context elements, or try to implement a way to skip over index context elements when walking up the tree.
