add support for turning off timeout on event listeners

Hi there. Great work on the library. I just have one fix I'm hoping to merge.

Basically sometimes I have elements that are inserted into the DOM before the 20ms window. They aren't caught by the insertionQuery listeners since the timeout hasn't finished yet.

So I added an option to disable the timeout. I only added it to the `every` fn. though, because on summary you will run into problems selecting parent elements since those might not have loaded yet.
