Add smart fee estimation functions

These are more useful fee and priority estimation functions. If there is no fee/pri high enough for the target you are aiming for, it will give you the estimate for the lowest target that you can reliably obtain.  This is better than defaulting to the minimum.  It will also pass back the target for which it returned an answer.
