Fixed case problem for phenotype relations.
Switched to using bud's url table to load reference dois, rather than using the doi column in the reference table.
Added doi to aux_disambig for references. This fixed #2457.
Merge branch 'integ' into protein-pasge-#2336

Conflicts:
	convert/convert_dev.py
	convert_other/convert_bioconcept_in_depth.py
Added related references to reference page. #2458
