Use slf4j api in all the xbean components and slf4j-api as the depdency ?

[Ivan]

Hi,
   I found that currently in xbean components, many log apis are used,
slf4j, commons-logging, and log4j. I would like to use slf4j api
everywhere.  Also, I think that we could depend on slf4j-api directly, as
not all the components need to run in OSGI environment.
   Thoughts ? If no objection, I would go ahead to change it.
