removeEffectsFilter tweaks

There's a great function, Actor:removeEffectsFilter, which doesn't get used that often. Partly because of the fact that it never was quite powerful enough to be used. This commit adds a couple of extra checks for it, and makes staple "strip sustains" and "strip effects and sustains" functions, too. I only converted Wild and Primal infusions because I don't feel like testing about 10 talent trees that currently contain interactions with random effects. The original contributors of that trees may decide to switch to use the new interface, though, and addon developers are welcome as well.
