* add more "known updates" to the NUS class. now your can specify "3.4u" or similar instead of a TID and it will try to download all the titles that would have been in that update. the lists of titles were taken from wiimpersonator logs and when those were missing, from disc update partitions. thanks to markhemus and rduke for helping make the lists * NUS tool will now make sure there is a valid setting.txt in the nand after it is done installing titles to it
