Add methods to DigestUtils to generate hex from MessageDigest et. al.
*This PR replaces #7 which was associated with the wrong issue number*
This PR adds methods to DigestUtils to make it easy to generate hexadecimal
strings from:
- MessageDigest,
- DigestInputStream,
- DigestOutputStream.
If the underlying digest supports ```clone()```, a clone is created
before calling ```MessageDigest::digest``` to avoid resetting the state. If
this cannot be done, the original digest is used.
[Although clone is optional for MessageDigests, it seems to be almost
universally supported (e.g. both the Sun and the IBM providers implement clone
for their concrete digests) ]

Add methods to DigestUtils to generate a hexadecimal string from a
MessageDigest, a DigestInputStream, or a DigestOutputStream. If the underlying
digest implementation implements clone, a clone will be created before
extracting the digest to avoid resetting it.
