Removes memory leaks on the parse
- Parser location is now a custom class. It holds a shared pointer
  with the file name; If the parser fails, the resource is deleted.

 - To follow the parser change, the Rule class now holds the file
  name in a shared pointer instead of a unique pointer. As a shared
  pointer we avoid duplication of the file name in memory, plus,
  it frees itself when not in use anymore.

 - Operator init also accepting the filename as a shared pointer.

 - Driver is treating m_location was privative. Now it holds a
  std::list<std::shared_ptr<yy::seclang_parser::location_type>>
  instead of: std::list<yy::seclang_parser::location_type *>.

 - Fix: addSecRule on Driver() was changed from RuleWithAction to
  RuleWithOperator.

 - Minor changes on the regression and rules-check utility to force
  deletion of resources even when they fail.

 - Couple of virtual destructors were placed to force the shared
  pointer decrementing on shared variables.

 - Deleted constructors for copy were placed for the sake of
  readability.
