  // this handles changes to how the URL works after 2.2.0
  //
  // in 2.2.0, "hasCustomUrl" does not exist and "url" is only used when the mod
  // id is invalid, although it can be set at any time in the mod info dialog
  //
  // post 2.2.0, a custom url can be set on any mod, whether the mod id is
  // valid or not, so an additional flag "hasCustomURL" is required, with a
  // corresponding checkbox in the mod info dialog
  //
  // there are several cases to handle to make sure no data is lost and to
  // determine whether the user has set a custom url before:
  //
  //   1) some mods have an incorrect url set along with a valid mod id;
  //      there is apparently a bug with the fomod installer that can set the
  //      url of a mod to a value used by a _previous_ installation
  //
  //   2) it is possible to set the url even if the mod id is valid, in which
  //      case it is saved, but never used in 2.2.0
  //
  //   3) opening the mod info dialog on the nexus tab for a mod that has a
  //      valid id will force the url to be the same as what the plugin gives
  //      back
  //
  // the algorithm is as follows:
  //   always read the url from the meta file and store it so this piece of data
  //   is never lost; the problem then only becomes about whether to enable
  //   hasCustomURL
  //
  //   if hasCustomURL is present in the meta file, just read that and be
  //   done with it
  //
  //   if not, then the flag depends on the mod id and the url
  //      if the mod id is valid, the custom url is disabled; although the url
  //      could be _set_ by the user when a mod id was valid, it was never
  //      _used_, so the behaviour won't change
  //
  //      if the mod id is invalid, the url should normally be empty, unless the
  //      user specified one, in which case hasCustomURL should be true
  //        (the only case where this fails is if a mod id was valid before and
  //        the user visited the nexus tab, in which case the url was set
  //        automatically, but then the id was manually changed to 0
  //
  //        in that case, the mod id is invalid and the url is not empty, but it
  //        was never set by the user; this case is impossible to distinguish
  //        from a user manually entering a url, and so is handled as such)
