[Rd] Requirement for pandoc 1.12.3 in R 3.1.3

Dan's suggestion to get latest pandoc got me part of the way to a
workaround. The other part was removing references in the vignette to
alpha versions of some software.

For info: pandoc 1.13.2 seems to have some bugs for conversion of LaTeX
to html or epub still (or at least the error messages point to the wrong
place). However, these are in work I'm doing outside of R, and I'll
pursue them with the pandoc developer(s).
