Completed new common_log for sim_engine

Provides easy access to log recorders for modules using the
global sim_engine log. To get a log_recorder for your module
use the following syntax:

 log_recorder mylog(common_log::get_reference()("moduleName"));

See the unit test in common/logger for more information on
using the log facility.

Unit tested and ready to go.
