Case-insensitive citation abbreviations

[xalexalex]

Hey,
this is actually an old issue in pandoc-citeproc.
I checked yesterday and it is indeed still present. Basically, if the abbreviations.json file has "Modern Pathology": "Mod Pathol", but your bibtex entry is journal={Modern pathology} (lowercase P), it won't get abbreviated.

I'm no haskell expert, but if you point me towards the right place in the code, I might try drafting a PR.

Thanks in advance!

Sure! I think the best approach would be to replace Text with CI Text in the definition of the Abbreviations newtype in Citeproc.Types. Note that we're not exporting the externals for Abbrevitaions, so this wouldn't be an API change.
