	* png.tcl: Fixed a problem with the reading of crc data from png
	  files. The 'binary scan' may return a negative integer, but the
	  check is against unsigned data. Added code to check for this and
	  compute the proper unsigned number for correct comparison.

	* png.test: New file. A testsuite for the module. Incomplete.
	  Tests the validation, signature, retrieval of image information,
	  and of timestamps. The image files used are from the official
	  PNG testsuite.
