Removing usage of LogKitManager / LogKitManagable

[Peter Royal]

Anyone opposed to removing the usage of the LogKitManagable interface 
from HEAD?

The impact is that Loggable components would no longer be able to 
receive a logger, and on the flipside, Log4J support will be much 
easier to implement as all logging-impl specific code is then in 
CocoonServlet, Cocoon.java and all other classes will just deal with 
the Avalon facade.
