Add priority to event prefilters. (#1378)

This allows for prefilters to be processed in order of least to highest
complexity, leading to more efficient processing of events that don't
match. For instance, matching a regex is more expensive than matching a
boolean, so we check the boolean first, and if it doesn't match, then we
don't try the regex match, whether or not it would match. General
prefilter types have been given a default complexity, but as every
prefilter is different, it's also possible for individual overrides to
provide a custom priority instead.
