Moved bibliography processing into readers.

Previously this was done in src/pandoc.hs, which made it difficult
for library users.

* Removed readerCitations in ReaderOptions.
* Added readerReferences and readerCitationStyle to ReaderOptions.
* Moved use of processBiblio from main program to the
  markdown and LaTeX readers.
