Generic AmiGO linking function. A real function mind you--not an object generator.
TODO: maybe this should actually be under bbop.html so we could make use of the anchor tag stuff?
NOTE: A lot of this is lifted from the (defunct) amigo.js package. However, the future should be here.
NOTE: This should pull data from something like amigo.data.xrefs instead.
