	* app/plug-in/plug-in-progress.[ch]: renamed plug_in_progress_init()
	to plug_in_progress_start() so it matches plug_in_progress_end().
	Added g_return_if_fail() to all functions.

	* app/plug-in/plug-in.[ch]: plug_in_new(): require the passed
	path to be absolute. Removed plug_in_search_in_path(). Replaced
	some if(plug_in){...} by g_return_if_fail(plug_in!=NULL). Cleanup.

	* app/plug-in/plug-ins.c: plug_ins_def_add_from_rc(): refuse to
	add plug_in_defs with non-absolute paths (should never happen).
	Misc cleanup all over the place like s/GSList *tmp/GSList *list/.

	* app/plug-in/plug-in-params.c: cleanup.

	* tools/pdbgen/pdb/plug_in.pdb: changed accordingly.

	* app/pdb/plug_in_cmds.c: regenerated.

	* app/gui/brush-select.c
	* app/gui/gradient-select.c
	* app/gui/palette-select.c
	* app/gui/pattern-select.c: some code review & cleanup.
