FileRepo stuff strange return values

[elifoster]

The file repo methods return some strange things. Particularly, they all return Hashes instead of arrays. For example

{{"name"=>"hydra-commons",
  "url"=>"https://hydra-media.cursecdn.com/ftb.gamepedia.com"}=>nil,
 {"name"=>"local",
  "url"=>"https://hydra-media.cursecdn.com/ftb.gamepedia.com"}=>nil}
