Implement amsthm-like Theorem environments with Maruku.
Support is based on Maruku "div"s with special class-names.
Classes
num_*
produce numbered environments, and
un_*
produce un-numbered environments, where * is one of
theorem (for Theorem)
lemma (for Lemma)
prop (for Proposition)
cor (for Corollary)
def (for Definition)
example (for Example)
remark (for Remark)
note (for Note)
In addition, the class
proof
produces a Proof environment.
The LaTeX export works as expected, and these also work in the S5 view.
Bumped version number.
