Subject: [PATCH] Update info.sh

* Works properly on Fedora 17 now, possibly other RPM-based distros
* Add GetDistro() function taken from logic in stack.sh
* Source functions in tools/info.sh
* Use GetDistro() and get_packages() in tools/info.sh
* Report all installed pips
* Don't sort localrc output as order is important
