A default set of prelude-like filters and the means to construct your own.

Please be aware that some of the defaultFilters are assumed to be present (for example during loop unrolling and assignment of else branches via empty).

It's recommended you supplement the default filters rather than replacing them completely. (But hey, it's your call!)
