Allow import/export on a per- form_id basis

Issue Summary

I use this module frequently because of its ease of use and I find myself performing the same tasks again and again. It would be very helpful to be able to export and import form filter definitions (ala http://drupal.org/node/479756). This would also be very useful for building advanced Features which would have limited "hook_form_alter" capabilities.

Thanks,
