Adding information about shortcut classes to "Regular Expression Syntax" section. #445

This took me forever to figure out, it would be awesome if you put it in the 
documentation.

Note that character class shortcuts (IE \w, \W and \s) are *NOT* valid POSIX

FreeBSD or older Mac OS/X versions).

I've attached a patch for the Wiki page.
