MacGui: Add "Auto" to audio sample rate selections

- Auto simply uses the input audio's sample rate
- Built in presets updated to use Auto for all but device presets which still use 48.
- prepareJob now uses the selectedIndex's tag from the sample rate NSPopUp instead of libhb's built in array of sample rates
