the 'Proclavity to croak' release

• The docs for Time::Local talk about the 'proclavity to croak'
  which basically means the module croaks easily. So did this
  one until now.
  

Until now, if you allowed a user to specify a pattern and they
entered one that was non parsable, this module would croak
causing your script to croak. This is a Bad Thing (tm).

The behaviour now remains the same, however if you set
$DateTime::Format::StrpTime::CROAK to false, methods will
return undef rather than croaking.
$DateTime::Format::StrpTime::errmsg will tell you what went
wrong.

The default is to continue to croak. This means you have to
delibrately turn it off. Hopefully you'll change you script
to do this at the same time you change it to check the
return values of the methods :)
