$MCACHE - rework memcached support - some rework on eaccelerator

Browse source 
We now have a wrapper memcached support class to handle
initial connection setup, provide the common denominator
calls, plus getforfill() and friends.

The eaccelerator class now returns false to match memcached. The
downside of this is that we cannot store booleans as a false value
is indistinguishable from a false that indicates error or 'key not
found'.
