Renamed item.fileSize to item.size in fs.list() return value, enabled 3D in the editor, added a lot of missing documentation

For the return values, I followed this rule: if the fuction returns true on success, it should return false, error on error; for every other case it should return nil, error on error.

Also, who doesn't want to edit code in 3D ? The line depth depends on the indentation level.
