Don't display the translators tab unless there is stuff to show.

2003-01-28  Glynn Foster  <glynn.foster@sun.com>

	* src/about.c: Don't display the translators tab
	unless there is stuff to show.

	* src/entry.c: Add sanity NULL checking.

	* src/tree.c, src/zenity.h: Add support for a new
	--editable option.

	* src/main.c: Add support for new --editable option for
	the List dialog. Merge in the list of Gtk+ options into
	the popt table - ripped this from libbonoboui, thanks to
	James for pointing this out.

	* src/zenity.glade: Make the translatable strings less arse.

	* TODO: Update accordingly.
