Add spec file so we can create RPM packages. (#37)

* change install.sh so it does not run sed on the scripts, but creates a config file

* use the config file if it exists, falling back to the same defaults as we had before if the config file is not present or an option is not set in it

* Document config file

* Create first version of a rpm spec file and config

* Change location of the configuration file so its no longer redhad/centos/awslinux specific

* Add config file to repo, and fix spec file so version is correct according to https://fedoraproject.org/wiki/Packaging:Versioning
