Tim Kelsey 713949fe69 Rule selection rules
This makes the following changes:
- riles are identified by an ID
- include / exclude list now work
- rules are selected based on these lists
- blacklist rules are broken out into methods
- rule constructors now take the config map
- config file can be used to select rules
- CLI options embelish config selection options
