Upgrade to Module-Pluggable 4.2

The core build process cannot use Build.PL since Module::Build and/or its
prerequisites may not have been built yet, so EXCLUDE that and retain our
(already CUSTOMIZED) Makefile.PL instead for now.

+=head1 BEHAVIOUR UNDER TEST ENVIRONMENT
 
+In order to make testing reliable we exclude anything not from blib if blib.pm is 
+in %INC. 
+
+However if the module being tested used another module that itself used C<Module::Pluggable> 
+then the second module would fail. This was fixed by checking to see if the caller 
+had (^|/)blib/ in their filename.
+
+There's an argument that this is the wrong behaviour and that modules should explicitly
+trigger this behaviour but that particular code has been around for 7 years now and I'm 
+reluctant to change the default behaviour.
+
+You can now (as of version 4.1) force Module::Pluggable to look outside blib in a test environment by doing either
+
+        require Module::Pluggable;
+        $Module::Pluggable::FORCE_SEARCH_ALL_PATHS = 1;
