Find logging configuration relative to environment

Previously, the scripts all looked for the logging configuration in
$XD_HOME/config (or %XD_HOME%/config).  This caused issues because it
meant that if you moved all of the configuration and overrode
$XD_CONFIG_LOCATION (or %XD_CONFIG_LOCATION%), the logging
configuration changes would not be found in the new location.  This
change updates the scripts to look for logging configuration in
$XD_CONFIG_LOCATION (or %XD_CONFIG_LOCATION%).
