- fixed rt.cpan.org#24232 - import ENV vars only if defined

	- fixed rt.cpan.org#20742 - dont' overwrite a var if re-defined
	  in current scope, interpolation failed for re-defined vars and used
	  the value of the var defined in outer scope, not the current one.

	- fixed rt.cpan.org#17852 - a 0 as blockname were ignored. applied
	  patch by SCOP to t/run.t to test for 0 in blocks.

	- applied most hints Perl::Critic had about Config::General:
	  o the functions ParseConfig SaveConfig SaveConfigString must
	    now imported implicitly. This might break existing code, but
	    is easily to fix.
	  o using IO::File instead of open().
	  o General.pm qualifies for "stern" level after all.

	- added much more tests to t/run.t for 'make test'.

	- using Test::More now.
