asciidoctor-bibtex 0.6.0

asciidoctor-bibtex is an Asciidocotor extension that adds bibtex support for AsciiDoc documents. It does so by introducing two new macros: `cite:[KEY]` and `bibliography::[]`. Citations are parsed and replaced with formatted inline text, and reference lists are automatically generated and inserted where the `bibliography::[]` macro is placed. The references are formatted using styles provided by CSL.
