Update to 1.76:

version 1.77 [sic!]: Tue Apr 10 09:25:29 CEST 2007

	- The tag (field label) casing is "normalized" which is not
	  required (as the comment in the code told), but a mis-
	  feature.  The feature will not change, to avoid breaking
	  existing code. Original report by [Matt Swift]

	- Do not ignore unknown argument to Mail::Internet::new(),
	  but complain about it [JPBS]

	- Document that the \n is still after a header line, but folding
	  is removed. Suggested by [Roberto Jimenoca]

	- Document that unfolding is too greading, taking all leading
	  blanks where only one should be taken. Suggested by
	  [Roberto Jimenoca]

version 1.75: Wed Jun 14 15:30:25 CEST 2006

	- [Mike Lerley] reported that environment variables are not
	  thread-safe in mod_perl.  Therefore, he required to pass the
	  sender of the message explictly on qmail's command-line.
	  His addapted patch included.
