[feature request] checkbox for blocking reminders from being downloaded (or blacklist)

[kbgashren]

A feature that allows to exclude submissions that have certain keywords (either as tags, or as part of the submission-title) would be nice to have.

I don't know how feasible it is to implement, since FA does not force people to use tags, nor has a separate field to mark submission as a reminder (those are the most annoying, if I don't remove them by hand before downloading, I will end up with several pictures that are exactly the same, but most of them are reminders, so they're just take up space) but even the simple "blacklist" from just the submission name would be something.

Maybe a variable with flag, that would be checked around AppCore.cs line 436, where the title, date etc. are processed?

Looking at FA submission page, implementing tag blacklist over that should be (relatively) simple, as they're wrapped in <section class="tags-row"> with each tag being in its own <span class="tags">
