Added tables for directory locations for deb+rpm and zip+tar.gz installs

I raised an issue for this but Clint mentioned it's not required, please let me know though if you want me to sign the contributing agreement.

Per the title, I've written down the specific directories being used by various install methods, hopefully it'll be of use to newer users. I wasn't able to find and indication of a work directory for the zip/tar.gz install though, not sure if that is by design.
