two page cheat sheet for Salt states

to produce PDF use `pdflatex` command like this:

```
pdflatex salt.tex
```

It would be nice, if the PDF can be hosted somewhere in saltstack.org 

May be here ? http://saltstack.org/static/salt-cheatsheet.pdf

The content is based on this wiki page: https://github.com/saltstack/salt/wiki/Cheat-Sheet
Thanks to authors!
