Init.pp now has multiple checks for the OS family and version.
Error.pp supports multiple error messages.
Tuned.pp was the old init.pp. Only major change is a fix to prevent Fedora from crashing on ktune.
Tested on Scientific Linux 6, CentOS 5 and 6, Fedora 18, SLES 11*, Debian 6*.
*(gracefully notifies user and makes no changes).
