Improving usability, massive refactoring.

* Moving all Drools code into their own modules. This fixes ri-engine
  to acme dependency.
* Now they all inherit from their own parent, should be used by
  third party code too.
* Separating acme planning code into its own module.
* Splitting rules code from ri-engine into ri-base. ri-engine is now
  a pure launcher for modules.
* Dumping kogito for the most part, but it seems like the planner still
  requires that.
