Update p5-Net-Z3950-ZOOM to 1.28.

Changes from previous:
1.28  Fri Oct 15 13:34:41 BST 2010
	- In the test-suite, provide a more explicit report when the
	  scan identity test (display term == term) fails.
	- The displayTerm==term assertion is now case-insensitive, as
	  it ought always to have been: previously, the test-suite
	  relied on a specific implementaton detail of the
	  test-server, which has recently changed causing extraneous
	  test-suite failures.
	- Also in the test-suite for scan, remove the test that all
	  title-terms are in the general-term list, an assumption that
	  should never have been made.

1.27  Wed Aug 11 17:13:07 BST 2010
	- Support for Index Data build procedures, including making
	  Debian/Ubuntu and Red Hat packages from clean tarballs.
	- No upstream changes -- packaging only.

1.26  Tue Jun  8 16:43:29 BST 2010
	- Tweak the test-suite so that it works correctly on Fedora
	  Core 12 (2.6.31.5-127.fc12.x86_64).  For some reason,
	  attempts to connect to a non-existent host can fail with
	  ERROR_TIMEOUT and no addinfo, rather than ERROR_CONNECT and
	  the hostname as addinfo; and the number of terms to request
	  in a scan needs to be explicitly specified in an option.
	- Add "debclean" target to generated Makefile.
	- Remove extraneous and misleading old CVS IDs.
