More flexible configuration of the path to the source database

templates. There is a new configuration option in the script containing
the default path to the directory containing source database templates. The
value of that option will be updated during make install. Relative pathnames
are converted to absolute  pathnames with respect to the location of the
ser_dbtext.sh script.
