Update to 0.31:

0.31 Wed 14 Nov 2007
	- Upgrading to Module::Install 0.68

0.30 Mon 22 Oct 2007
	- Incremental release to get a newer and non-broken version of the
	  author-only tests.

0.29 Thu 23 Aug 2007
	- Correcting a test which only ran under AUTOMATED_TESTING,
	  apparently my release automation isn't doing what I think
	  it is doing.

0.28 Sat 18 Aug 2007
	- Dropping the Perl version requirement in 01_compile.t to 5.004

0.27 Sat 18 Aug 2007
	- Skipping one particularly evil test that we know fails on a few OS
	  unless AUTOMATED_TESTING is enabled.
	  These failures weren't worth preventing installation at all.

0.26 Fri 27 Jul 2007
	- Adding the _NONNEGINT function
