bencode: Simplify (*Decoder).parseListInterface() (#656) 
Preserve as much type as possible (it'll be converted to an `interface{}` anyway, but we can return `[]interface{}` instead of `{}interface` here).

901a8b1b36 Don't panic on int parse failures 
This means for UnmarshalTypeErrors we now include context. There are still some other error types remaining that are thrown up via panic.

fc4fab91f5 Switch to goimports import sorting

a4a123b04e Don't error on bencode dicts that can't be marshalled 
Have seen metainfo announce-lists that are lists of dicts. Possibly ignoring type errors with a tag would be smarter but I'm undecided.
