Changes between 1.0.0 and 1.1.0 [xx XXX xxxx]
*) Add algorithm specific signature printing. An individual ASN1 method
can now print out signatures instead of the standard hex dump.
*) Add signature printing for PSS. Add PSS OIDs.
[Steve Henson, Martin Kaiser <lists@kaiser.cx>]
More complex signatures (e.g. PSS) can print out more meaningful
information. Include DSA version that prints out the signature
parameters r, s.
