export media: editable resolution / frame rate / bit rate spin boxes

The three values are SpinBoxes (typed input + stepping): width & height
(0 = use the sequence size), frame rate in fps (0 = sequence rate),
bit rate in bit/s (0 = the codec default). The engine already accepted
arbitrary values, so the dialog now exposes them instead of the closed
preset lists. i18n across the 8 packs.
