Update to 1.22.

hashcash-1.22 - 08-Apr-2006 - Adam Back <adam@cypherspace.org>

[BUG FIXES]

hashcash-1.18 - 05-Jul-2005 - Adam Back <adam@cypherspace.org>

	* add a simpler minting API to make it easier to mint stamps
	  from VB scripting

hashcash-1.17 - 30-Mar-2005 - Adam Back <adam@cypherspace.org>

[BUG FIXES]

hashcash-1.15 - 12-Jan-2005 - Adam Back <adam@cypherspace.org>

	* make "Hashcash:" be accepted as well as "X-Hashcash:"
	  suggestion by Simon Josefsson <jas@extundo.com>.  This way
	  if/when the X- is dropped from hashcash headers we will not
	  have a backwards compatibility problem.  (Well not after
	  version 1.15).

	* implement the -Z option to compress stamps; in fact the
	  usage changed so -Z takes an argument: 0, 1 or 2.  0 = not
	  compressed, 1 = compressed but not so the counter + padding
	  is split, and 2 = very compressed, but slow.  (Due to a late
	  discovered bug 2 is the same as 1 for now until I can fix
	  that.)

	* added -O x -sv to request benchtest of core x only

	* make code work with -DOPENSSL, think this slipped during
	  integration of Jonathan's libfastmint as it uses some lower
	  level openssl APIs internally.  I fixed it but it might be
	  a bit openssl version specific, if they changed the state
	  fields at any point.  (This change coincidentally I think
	  should work around the linking with openssl problem that Hal
	  Finney <hal@finney.org> reported).

	* add libhashcash.a intermediate target to make hashcash more
	  convenient to link into other software on linux.  (A
	  suggestion from Hal Finney who was trying to link to his
	  RPOW system.)

hashcash-1.14 - 14-Dec-2004 - Adam Back <adam@cypherspace.org>

	* make hashcash -cX accept continuation lines starting with
	  space as well as tab

	* add library function to wrap lines and use it from hashcash
	  command line tool.

	* fix long vs time_t prototype mismatch that was giving
	  compile errors on BSD; also cleaned up some warnings that
	  can be obtained with gcc -Wall.
