	* libgimp/gimppixmap.c: fixed a gtk-doc comment.

	* libgimp/gimpenv.[ch]: new functions:

	- gimp_path_parse(): Creates a GList of strings from a searchpath
	  string and performs sanity checks.
	- gimp_path_to_str(): Creates a searchpath string from the list
	  returned by gimp_path_parse().
	- gimp_path_free(): Frees the list returned by gimp_path_parse().
	- gimp_path_get_user_writable_dir(): Returns the first dir in a
	  path where the user has write access. With this function the
	  "Save" dialogs of some plugins always show the plugin's
	  subdirectory of the user's gimp_dir instead of the read-only
	  global one.

	* app/datafiles.[ch]
	* app/gimpbrushlist.c: use the new functions and
	s/datafile_loader_t/GimpDataFileLoaderFunc/.

	* plug-ins/FractalExplorer/Dialogs.c
	* plug-ins/FractalExplorer/FractalExplorer.c
	* plug-ins/gfig/gfig.c
	* plug-ins/gflare/gflare.c
	* plug-ins/gimpressionist/gimpressionist.c: use the new functions.
