• Fixed bugs in the ProhibitCascadingIfElse policy.
  
• Added ProhibitExplicitReturnUndef policy
  
• Made ProhibitUnpackagedCode configurable so you can exempt scripts,
  which typically don't have an explicit 'package' statement.
  
• ProhibitPackageVars policy now exempts vars in ALL_CAPS. This
  is to permit common package variables like @EXPORT and $VERSION.
  
• Renamed "ProhibitStringyGrep and "ProhibitStringyMap" because
  the so-called string form doesn't really exist. Now called
  "RequireBlockGrep" and "RequireBlockMap"
  
• Corrected documentation on defining Policy names within the
  configuration file. This still isn't very clear and needs
  to be rewritten.
  
• Perl::Critic now requires PPI version 1.003, which has a few bug
  fixes of its own.
  
• Rewrite some code just to make Perl::Critic more self-compliant.
  
• Added test cases to verify the configuration functionality. These
  are not completely thorough and need more work.
