Gave effects their own collection, they no longer live in arrays attached to skills/attributes

Also improved the display of features and generally iterated on their manipulation.

Characters now fetch the relevant effects directly when making a calculation, simplifying almost everything.

Effects now store a reference to their source if they have one.

Effect names are now optional, they can be fetched from the source's name if the source exists.
