What:

Improved the ABT due to a valuable discussion with @rparisha2:

1. Blackboard can now share also all type of data. not only shared_ptrs
2. Blackboard methods (lookUp/declare) are now aligned with normal STL containers (get/set)
3. Conditions can be now combined with operators AND OR and NOT
4. All Nodes use now the same Conditions (Wait, Until, ConditionNode...)
5. Updated the styleguide of member variables for ABT
