2.33

- fixed rt.cpan.org#26333 - just return $con if env var
	  is undefined.

	- applied part of a patch supplied by Vincent Rivellino <vince@cuz.cx>
	  which turns off explicit empty block support if in
	  apache compatibility mode, see next.

	- added new option -ApacheCompatible, which makes the
	  module behave really apache compatible by setting the
	  required options.

	- a little bit re-organized the code, most of the stuff
	  in new() is now outsourced into several extra subs to
	  make maintenance of the code easier. The old new() sub
	  in fact was a nightmare.

	- fixed a bug reported by Otto Hirr <otto.hirr@olabinc.com>:
	  the _store() sub used sort() to sort the keys, which conflicts
	  with sorted hashes (eg. tied using Tie::IxHash).

	- fixed tie bug reported by King, Jason <kingj@newsltd.com.au>,
	  loading of the tie module didn't work.
