Extend component query behaviour: AND, OR, NOT

[fernandojsg]

Currently the query on the systems will look for entities with all the components on the list.

[Transform, Rotating] => Transform AND Rotating

We should be able to modify the query to do things like:

[ [Transform, Rotating], [Scale], [NOT(Transform), PulsatingColor]]
=> (Transform AND Rotating) OR (Scale) OR (!Transform AND PulsatingColor)

[fernandojsg]

I haven't seen OR used, for that it's better to use another query
