//  Name:  cnr_silent_ou
//
//  Desc:  This is the silent OnUsed handler for
//         devices that craft recipes. It does not
//         open a recipe convo dialog, but instead
//         automatically attemps to make a recipe.
//         Recipes are attempted first to last.
//
//         This OnUsed handler is meant to fix a Bioware
//         bug that sometimes prevents placeables from
//         getting OnOpen or OnClose events. This OnUsed
//         handler in coordination with the OnDisturbed
//         ("cnr_device_od") handler work around the bug.
