Changed typo
Added operator overloading to pf::MAC so that MACs can be compared
regardless of how the MAC was passed to the constructor.

E.g. 00:00:de:ad:be:ef eq 00:00:DE:AD:BE:EF should return true.
This differs from the behavior of Net::MAC.

Added an "in_OUI" method for convenience.
Allows to check if a MAC is part of an OUI regardless of case or
delimiter.
Modified get_oui to return the format expected by PF and added a
get_IEEE_oui method.
Added email alias for sponsor (Exchange and Postfix)
Bugfix: radius accounting was using the old _parseRequest and thus was
broken.

Fixed to use the new switch::parseRequest and radius::_parseRequest.
Added news item for the bugfix.
Added a new attribute as mail alias
