Test-More 0.71 "breaks" DBI and XML::LibXML

One of the improvements in Test-Simple 0.71 is that it "[f]ixed a problem with BEGIN { use_ok } silently failing when there's no plan set." Turns out that some modules like DBI and XML::LibXML have accidentally relied on the old behavior, so that if you have Test-Simple 0.71 installed, DBI 1.59 and XML::LibXML 1.64 will fail their tests. There may be others as well, but those are all that I know of for sure.

Addendum: It breaks my own WWW::Mechanize, too, but Mech has plenty of other things breaking for it as well, so it's not so bad.
