gtk.m4: When testing to see if glib exists, set LIBS="$GTK_LIBS $LIBS" NOT

gtk.m4:
	When testing to see if glib exists, set
	        LIBS="$GTK_LIBS $LIBS"
	NOT
	        LIBS="$LIBS $GTK_LIBS"
	because order matters - if the user specifies their own $LIBS to
	./configure, these need to be passed in last.

gtk/Makefile.am:
	Fix problems with gtktypebuiltins* getting rebuilt every single
	time 'make' was run.

gtk/gtkcalendar.c:
	Set 'week' variable to 0 to get rid of uninitialized
	variable warning. Better solution is to give it the right value
	somewhere :)

gtk/gtkclist.c:
	When computing optimum column size, don't subtract the borders.(?)

gtk/gtkcolorsel.c:
	Don't read past end of array.
