New releases of all hackages! + code tidies.

Revamp XML-Conduit-Stylist API to avoid hard-dependency on Haskell Stylist.

Add utils for implementing :target-within, ensure unlayered styles take precedance.

Integrate @layer support into core engine!

Parse @layer rules.

Tweak priority to be a list for the sake of cascadeLayers.

Remove Stylist-Traits APIs from Stylist Core, leaving backwards-compatible stubs.

Extract parser, datatypes, & traits into separate decoupling hackage.
