[Mediawiki-l] Activating Turck MMCache after installation

[MHart]

I enable mmcache on all sites - I have about 5 running on one server, all 
with mmcache enabled, without any problems. I did not, however, attempt to 
go back to sites that were previously setup and get them running with 
mmcache, rather I re-setup the scripts in a different folder and updated the 
server settings.
