Changes to let BABL find its extensions at run time when the BABL_PATH

2007-09-14  Kevin Cozens  <kcozens@cvs.gnome.org>

	Changes to let BABL find its extensions at run time when the
	BABL_PATH environment variable is not set.

	* configure.ac: Don't specify BABL_PATH in here. Renamed
	BABL_LIST_SEPERATOR to BABL_DIR_SEPARATOR.

	* babl/babl-extension.c: Include /lib as part of default BABL_PATH.
	Renamed #define's used to specify the path and directory separators.
	Use the values from config.h that were set when ./configure was run.
