Add functions to init and free the parsing options. Still not terribly

2003-01-06  Glynn Foster  <glynn.foster@sun.com>

	* src/main.c: Add functions to init and free the
	parsing options. Still not terribly pretty though.

	* src/tree.c, src/zenity.h: Handle --column
	argument.

	* TODO: Update accordingly.
