Ethan Atkins 6c4e23f77c Only persist file stamps in turbo mode 
The use of the persistent file stamp cache between watch runs didn't
seem to cause any issues, but there was some chance for inconsistency
between the file stamp cache and the file system so it makes sense to
put it behind the turbo flag.

After changing the default, the watch/on-change scripted test started
failing. It turns out that the reason is that the file stamp cache
managed by the watch process was not pre-filled by task evaluation. For
this reason, the first time a source file was modified, it was treated
as a creation regardless of whether or not it actually was.

To fix this, I add logic to pre-fill the watch file stamp cache if we
are _not_ persisting the file stamps between runs.

I ran a before and after with the scala build performance benchmark tool
and setting the watchPersistFileStamps key to true reduced the median
run time by about 200ms in the non-turbo case.
