Author tests should all check RELEASE_TESTING and/or AUTOMATED_TESTING

[rhebus]

Some of the xt/* tests check RELEASE_TESTING and/or AUTOMATED_TESTING but most do not. They should all make this check.

Mostly this can be implemented by copying Adam's template from  http://cpansearch.perl.org/src/ADAMK/Algorithm-Dependency-1.110/t/98_pod.t (see also  http://use.perl.org/~Alias/journal/38822 )

Note also the critic tests should probably only run under RELEASE_TESTING; we shouldn't be bothering CPAN testers with Perl::Critic failures.

Patch adding checks to xt/*

[rhebus]

The patch adds checks for RELEASE_TESTING and AUTOMATED_TESTING to all xt/* apart from Perl::Critic tests.
Perl::Critic tests only check for RELEASE_TESTING.

Fixed in r10378

I only did whitespace changes to it (spaces->tab). Thanks :)
