Assets - H-uru/moul-assets#241
Sets up the an SDL variable so you can set individual permissions for upload/pellet drops to everyone/member only/off

Requested by Cyan Shard operator to prevent pellet uploads in individual hoods

Adds new SDL variable to Neighborhood.sdl

0 <= Everyone can upload (Default)
1 = Members only upload
2 >= No one can upload

Relatively minor thing: the code looks like it would work for all imagers that pop up in the KI, not just the pellet imager. Perhaps the things in the script should be called ImagerPermissionVariable, CheckPermission, etc. instead, in case we later want to add permission checks to other imagers as well?

Your absolutely right, change made.

As of #1450, we could theoretically merge this immediately without breaking MOULa. However, I think there's probably a discussion to be had about what our repository's SDL should look like compared to the rest of the ecosystem, so we should probably wait until either after that discussion or the SDL is deployed to MOULa.
