Moved previous default (paper) compilation target for pandoc to its own
file (paper.latex) and saved the current default as a backup file.
This should fix some issues with compilation to PDF, especially with
vertical spacing and quotes which would fail intermittently otherwise.
Removed pandoc module, since its only purpose was to house a template
file which specifically targets writing pandoc documents for latex, thus
falling closer to bibtex modularity than making a pandoc module
necessary.
