Show both current and detected in menu bar and dropdown

Show both the Current and Detected sample rates and bit depths in the menu bar and dropdown.

If bit depth detection is enabled, show the bit depth for Detected, otherwise just show its sample rate.

Though, I think this needs to be an option. Not everyone might want to see both, such as users wishing for #84.

Indeed, but it goes hand in hand with #87 and #88.

If there is an option to disable the auto switching, and manually apply the detected then it helps to know what the current and detected settings are.

As to #84 it seems like you could do the whole range of no info (music note), just the current, just current with bitrate, or the complete current/bits detected/bits.
