Fix Commons Logging to Allow for System Property Configuration of use_tccl Behavior

<classname>use_tccl</classname> (Thread Context Class Loader) behavior was originally added to Commons Logging by appending <parameter>use_tccl=false|true</parameter> to the <filename>commons-logging.properties</filename> file. This configuration option was problematic for certain use cases where other <filename>commons-logging.properties</filename> files were present. <classname>use_tccl</classname> is now implemented using the system property <property>org.apache.commons.logging.use_tccl</property>. <classname>use_tccl</classname> perpetuates the original default value (true).
