feat(data): support soft-deleting FilterLists

[collinbarrett]

resolves #713

[collinbarrett]

Now, by adding a key/value to any entry in FilterList.json as follows, it will be excluded from the website/API but gives us the opportunity to easily re-add later.

"isDeleted": true,

Updated Wiki.

We can easily add this to any other entity (Maintainers, Tags, etc.), but I thought we should just start with the FilterLists themselves and see how it evolves.

FYI, @DandelionSprout ^

Nice to know. It'll probably come in handy sometime within the next month, but I can't give an exact date as to when.

Although presuming this is primarily meant for #1737 to begin with, it'll be used within 2 weeks.

Entries with "isDeleted": true, are dropped from "compressed" FilterList.min.json?

Ah, this: a4a7414 ?

@gwarser , We don't have a "compressed" FilterList.min.json that I'm aware of. But, this soft delete feature does remove the lists from being shown on the UI which gets its data from this API endpoint. https://filterlists.com/api/v1/lists

[gwarser]

I meant minified. And yes, I looked into https://filterlists.com/api/v1/lists in attempt to exclude these marked lists from by downloader script.
