Clean-up of SpamAssassin PMC/Committers

[Kevin A. McGrail]

One of the duties of the PMC is to maintain the quality of the community 
for SpamAssassin.

And one of the ways this is done is to give credit where credit is due.  
I therefore propose that all committers/PMC members that have not not 
committed anything since Feb 1, 2013 are moved to inactive in the 
CREDITS and removed from PMC list to better reflect those currently 
working on the project.  And while our official policy is six months 
(http://svn.apache.org/repos/asf/spamassassin/trunk/CREDITS), this 
cleanup hasn't occurred in some time so I wanted to be lenient and leave 
plenty of time for those concerned to work on and make a commit. I will 
assume lazy consensus for this task on 2/6.

Additionally, I'd like to continue moving people towards committer and 
PMC status.  If you feel you deserve karma to commit on the SA Project 
or to be a member of the PMC, please don't hesitate to discuss it with 
on or off-list.  Our project relies on volunteers just like you!
