Allow handler specific behavior to be added to the assembly wide behavior list

[Head0nF1re]

According to the docs:

Note: adding a [Behavior] attribute to a handler will disregard all assembly-wide behaviors for that handler, so any global behaviors necessary must be independently added to the handler override behaviors list.

This means that, at the moment, adding a handler specific behavior overrides the assembly-wide behavior list. What do you think about, in the future, adding an AddBehavior{Before,After} attribute that would allow someone to plug a handler specific behavior into the assembly-wide ones? Food for thought but maybe even a WithoutAssemblyBehavior to remove a specific assembly-wide behavior for a handler?
