Links export correctly; blocks do not

[quarkQuark]

I've tested this with both the built in rremark link type and local definitions.

• rremark:foo correctly appears red in Org Mode, and correctly exports to LaTeX as {\color{red}\bfseries foo: foo( Aim for success! )} . I don't know if this syntax allows for changing the keyword arguments.

• #+begin_rremark ... #+end_rremark blocks are highlighted in Org Mode (so it definitely recognises them), but simply exports to LaTeX as \begin{rremark} ... \end{rremark}. It also seems to ignore the block name and keyword arguments.
