While debugging some strange cases with file-store options, I ran into some issues that are explained in the docs but could lead to confusion.

We want to make sure that we emphasize in the docs how different the pure `file-store` section is compared to the `files` type for EVE. Also a bit more explanation on each of the config settings and which work in both sections and which do only work in the `file-store` section. Same with impact if yo set different settings on both, like global override. So for example `force-magic` being set to true in either of those will make it global, `force-hash` will add hashes to the list (md5 in eve, sha1 in file-store results in both being enabled).
