Title: Add irony mark in the markdown cheatsheet.

This is a punctuation mark used to indicate that a sentence should be
understood at a second level.
Two unicode characters can be used :

* U+061F, ARABIC QUESTION MARK
* U+2E2E, REVERSED QUESTION MARK

I chose the second because of the meaning closest to the concept of
irony and not the first which would be rather a diverted use.
