Make Match follow the Strategy pattern

[hjorthjort]

The Match class should have variable representing it's strategy towards saving matches: whether they should be ranked or unranked. This could be a boolean, or a Strategy object, which would give some added complexity but also flexibility. This object/boolean should be passed along to wherever in the system rankings are updated, perhaps through the event bus.

This will be solved in another way. Closing.
