More filtering granularity

Previously, you selected a single filtering value. Artworks that had NSFW levels between the safest and the chosen were served to the user.
This update allows you to select any arbitrary combination of filtering levels, i.e. if you only want R18 pictures you select only the R18 level.

Ranking updates modes now its own distinct two filtering levels, in accordance to what it actually is in practice. Previously, ranking updates modes shared the same filtering levels as the auth modes, leading to confusion.

There is curently no checking to see if the filtering level changes.
