Detect desired vs. actual sample rate mismatch

With some soundcards it's possible to change the sample rate without Reaper's knowledge. If a recording is made in this state, the resulting WAV file is stamped with the wrong sample rate. I suggest:

- Reaper checks the incoming samples/s vs expected samples/s.
- If there's a mismatch of > 2% or so, Stop the transport and post an error.
- (Note there can be large mismatches in certain situations, like having a WC slaved from a tape machine in FFWD. There should probably be a way to disable this check. I recommend an option on the error box for "Ignore this error for the remainder of this session" or similar.)

(How does this happen? In my case, I'll be in a Reaper project happily working at 48k. I'll switch to something else (browser) which plays a sound at 44.1k, at which point my MOTU driver switches to 44.1. Back in Reaper, I'll hit record, and things are not quite right!)

I've had some big problems with this myself Reaper should warn you when the sample rate has changed outside of reaper at least.
