expand the tests, and provide more targets for running tests...

make addinfo.sh better when updating the database.

have addinfo.sh use the newly created minimizer and verification
functions in snapaid.sh...  update snapaid.sh to allow sourcing
so these functions can be reused...

Implement quoted-printable decoding, so that was can parse emails
encoded...

The above was needed to support verification of signatures when the
email is signed w/ a detached signature...  The signature is over
the quoted-printable email, but to get the hashes, needed to be
decoded...

Improve the hash detection to use a full regular expression to prevent
SHA512 at the begining of text from being parsed..

fix mispelling of bciroot...

print warning if a rev is invalid, so it can be detected sooner..

revisions...

This likely messes up formatting, and those fixes will be next...

for RELEASEs...

include vm type for RC/BETA

This is a set of scripts to make an index of all the snapshots, and
the message-id of the email that contains the hashes...

There is also the utility itself which uses this index to both find
out what snapshots are available for d/l, and to verify any snapshot
that may have already been d/l'd.
