Changes for Inform 7 (build 6L02)-It builds! Yeah!

Various changes to allow for the story to be built in the new Inform 7
(build 6L02).
File "/Users/redclaw/Documents/Inform/Flexible-Survival new/Flexible-Survival.inform/Build/auto.inf"; Line 10327	# Error:  No such constant as "PrintText"

(v) To print a text, use one of these:

	TEXT_TY_Say(x);
	print (TEXT_TY_Say) x;

Some old extensions call a routine called I7_String(x); this still exists,
and does the same as TEXT_TY_Say. Another routine in past builds was called
PrintText(x), and although this still exists, it has been renamed

	PrintI6Text(x)

since it prints a packed string or calls an I6 routine, but won't work on
the new I7 text value.
