Refactored policy system, fixed config file parsing inconsistencies.

- LocationPolicy is now an extension of Policy
- Policy.parse() is now PolicyParser mapped in PolicyParsers.
- NodeValueParser was merged with DataShifter
- More code small changes to enable the project to work with this new configuration.
