Escape token

[jfmrm]

In some cases we should be able to scape a token, as the default tokens are fairly common chars like '/', so we should be able to make something like '\ /' for it to render '/'.

(fun fact: I had to edit this text because Github has scape the '\ ')

You are right: this should be fixed, it should be fairly easy :)

I can try to make this PR, but my JS is pretty rusty. No promises here haha.
