Remotes Module: add (preview) implementation for menu action "fetch -> all remotes"

Also fixes a compile error due to a double closing bracket.

Caution: This currently *only* works within a repository context (static cast to RM::Repo)! If used in other contexts, MGV might crash or not behave like expected!
