Add support for raw-domains lists and syntax

[DandelionSprout]

As a long-time listmaker for a lot of extensions, and who see the potential in uBlackList, I'm wondering if it'd be feasible to add support for (or a syntax alias for) raw domains, e.g. for lines like simply example.org to be considered valid entries?

It would make it easier to utilise the list subscription feature, with https://filterlists.com/ showing 688 raw-domains lists, but only 3 match-pattern lists (At the time of writing referred to as "MinerBlock" syntax on that site).
