Async/incremental link validation.

Mostly working with the webapp, but the webapp needs 
to check for an null pointer to ensure that some
result is ready.   Other more minor wrinkles exist,
such as capturing the number of files checked and
displaying the version validated; this may be different
from the latest snapshot if the validation gets behind
the checkins for a while.
