[O] org-mode pretty entities has \perp but not \parallel

[Brady Trainor]

Hi, I expected \parallel to work after success with \perp. That is, I've 
executed in buffer M-x org-toggle-pretty-entities RET, and I expected to see 
\parallel as unicode ∥, since \perp is overlayed (correct term?) with ⟂. 
Though, the former is pretty hard to see, so maybe it was decided against.

I just tried exporting to HTML (and MathJax), and it looks like the LaTeX 
delimited symbols should be either $\parallel$ or $\|$. So simply writing $||$ 
in ones' notes would /not/ be the same.
