[FR] Add Ability To Blacklist / Block Individual Items In Library

[Suburban-Vampire]

As implemented, there is already a UI mechanism to Favorite individual wallpapers.

For a variety of compatibility and troubleshooting reasons, it would be helpful to have basically the same thing, but a second button that just allows the user to flag a specific item found in the library to explicitly say "DO NOT load this item, skip it".

My use case: I keep having some of the stock wallpapers and RGB wallpapers I never wanted showing up in my library even after removing / deleting them. Some of these crash the plugin and/or plasmashell, so the easiest approach is some mechanism to tell the plugin to not load a list of selected items from the library.

Alternatively, an option to skip / disable the built-in wallpapers would also be nice.
They are ALL things I don't like the look of and get rid of, and many of them currently break or don't display correctly in current builds.
On my system, I'm finding them in

~/.local/share/Steam/steamapps/common/wallpaper_engine/projects/defaultprojects/
