Add further samplig rates to drop-down box

I know that the user can type in any chosen rate, but it would be convenient for users of M-Audio Delta Audiophile 2496 and 192 cards (and possibly for other users of Audacity) to have rates of 88200, 176400 and 192000 added to the drop-down box. I assume this would be a trivial modification to make, but it would enhance useability.

If you go to the Quality Preferences you can select “Default Sample Rate” which will then always be used for new projects.
