sort of references should disregard capitalization

In the references section, when sortrefs="yes", the sort should be alphabetical without regard for capitalization. (Apparent exception is that RFCs get listed first, rather than being incorporated into the sort; that's fine.)

This ticket is similar to #255 regarding the index. And perhaps related to the fix for #250.

This example is from an author-submitted XML file.

Correction. Should have been with sortrefs="yes".

Desired output as in the ticket (with RFCs incorporated).

(Disregard my note about "apparent exception".)

Fixed in [1930]:

Made the reference sorting when using symrefs=yes and sortrefs=yes case-insensitive by mapping the reference keys to lowercase. This is correct for ASCII keys but not necessarily for non-ASCII keys, depending on locale. Fixes issue #295 (for now).
