Subject: [PATCH v2] get_maintainer: Add --prefix option

The --prefix option adds a Cc: prefix by default infront of the email
address so it can be used by other Scripts directly instead of adding
another wrapper for this.
The option takes an optional argument so "--prefix=Bcc: " is also valid.
Since it is expected to be output an email address it implies
"--no-roles --no-rolestats".

I don't see a problem with lists but I think it would make sense to
imply also "--nomoderated" once available.

v1…v2:
	- use --prefix instead --cc with "Cc: " as the default argument
	  if not specified
	- imply --no-roles --no-rolestats
