2008-04-21  Lucas Rocha  <lucasr@gnome.org>

	Add support for file filter in file selection dialog through the new
	--file-filter command line option (Fixes bug #409843).

	* src/option.c, src/zenity.h: added supporting variable and new 
	GOptionEntry entry for the new command line option.
	* src/fileselection.c (zenity_fileselection): add file filters based
	on command line input.
