[patch] use mkstemp instead of the deprecated tempname

[Paolo Borelli <pborelli katamail com>]

Compiling nautilus I noticed:

nautilus-application.o: In function `save_session_to_file':
/home/paolo/cvs/gnome2/nautilus/src/nautilus-application.c:1454:
warning: the use of `tempnam' is dangerous, better use `mkstemp'

the attached patch switches the code to use g_mkstemp

ciao
	Paolo
