Dragon Warrior II: Main Script F2 Fix

Dragon Warrior II's $F2 script control code is broken: if the number in RAM $8F-$90 is 1, it's supposed to print nothing, otherwise it's supposed to print "s". However, if the number in RAM $8F-$90 is 1, what it actually does is trigger a string end, which results in the game displaying text like "And earned 1 piece" instead of "And earned 1 piece of gold.".

This patch fixes the bug so that when $8F-$90 is 1, the $F2 control code prints no text instead of terminating the entire string. Note that the bug is undetectable in the original game since the $F2 control code is only used in combination with gold amounts and there is no way to change your gold amount by exactly 1, so this patch will be of limited interest to non-hackers.
