Removed runtime dependency from commons logging.

Now the PoiLogFactory will try to create a logger using the System property
named "org.apache.poi.util.POILogger".

If it fails, the NullLogger is used.
There is also a basic SystemOutLogger and the former CommonsLogger.

Haven't checked the code that much, but it compiles and POI works.
