Feature: Stash ID Count Filter

[Gykes]

This PR adds a new filter of "Stash Id Count" in the edit filter modal. This allows users to user greater than or less than to check for stashID counts against scenes.

I decided against adding this to the sidebar as we dont current have a decent UI display similar to the slider. I feel like the slider wouldn't be good for this but I can do it that way if people want it.
