fix testing of coercion with and without "Z" (test fix was incomplete in v0.12)
use unique strings to better diagnose failure reports
canonicalize timestamps; drop ego lines
ensure namespaces are set up properly

Add clean namespaces test, disabling it when needed; this test passing is
conditional on the version of MooseX::Types that installs declared types as
subs in the declaring class, but not in the importing class, so
namespace::autoclean works properly.
run moose-outdated in tests
tighten up entries
switch to my pluginbundle; fixes various encoding issues
these files are not being kept up to date - best to delete until we find what will update them
add irc and mailing list info to metadata
make timezones distinct, for easier deciphering of failing test reports
