function drush_migrate_deregister in Migrate 6.2

Same name and namespace in other branches

1. 7.2 migrate.drush.inc \drush_migrate_deregister()

Deregister a given migration, or all orphaned migrations. Note that the migration might no longer "exist" (the class implementation might be gone), so we can't count on being able to instantiate it, or use migrate_migrations().
