Name: Logging-kph.43

Merged SimpleLog and Logging.

The names of classes have changed so if yoo happen to have SimpleLog
loaded it should not interfere.

Essentially the architecture is:

LogCurrent provides the front end and the per process buffer
LogAdaptersSet provides nested sets of emitters with filtering
Anything that implements #logTime: stamp line: line level: level
category: category sender: sender pid: pid
can be an emitter.

SLLog is not needed.
The set up is more flexible, providing per process log configurations.
The structure is more logically consistent. There are less convenience
mehods to start/stop things at present.
