[PATCH] Add Rmarkdown.

[Ricardo Wurmus]

These three patches add Rmarkdown and dependencies.

The last patch that adds the “r-rmarkdown” package also changes the
import of “(gnu packages xml)” in haskell.scm to be less specific.  The
“#:select” phrase triggered an error due to circular package module
dependencies.  I hope it’s okay to put these two things in the same
patch?
