Allow Multiple Trigger / Action Filters to apply to the same layers.

[jcarlson]

If I add a Message Action to my list widget to filter another layer, I can only set this up to act on the basis of a single field pair. That is, LayerA.fieldB == LayerC.fieldD.

If I add a second action between these same layers, LayerA.fieldB == LayerC.fieldE, it seems that the first message is ignored in favor of the second.

I'd like some way to add multiple trigger/action pairs. I can think of a couple different methods:

1. Allow more than one field to be added to the message action
2. Have the framework honor all filters when multiple are defined, and give users an option for them to apply in an AND or OR manner.

At the moment, I can't see a decent workaround to this.
