Title:
  Provide a function to undo all upgrades of proposed packages

Status in software-properties package in Ubuntu:
  Confirmed

Bug description:
  While packages which are upgraded by versions delivered by a PPA are
  easy to downgrade with `ppa-purge` an equivalent function is missing
  for packages installed from `proposed` after it has been activated.
  Afaik the overview provided at
  https://askubuntu.com/questions/59443/how-can-i-revert-back-from-an-
  upgrade-to-the-proposed-repository is still the current state.

  The switch to `proposed` can be an easy way to fix issues, however
  once the fix makes it into an `-updates` repository it is a legitimate
  use case to stop using `proposed` packages since they can be
  troublesome.

  It'd be nice to automate the function provided by the scripts listed
  in the askubuntu.com post in a maintained official Ubuntu software.
  Most of the functionality is probably provided in `ppa-purge` already.
