Increase the maximum number of menu options from 10,000 to 100,000 to
accommodate configurations of more than 10,000 things (e.g. sub-boards) in a single menu (e.g. message group). This brings this value over the 16-bit thresholds (0x7ffff and 0xffff) where problems could happen if short's/int16's are used to capture the return value of uifc.list(), but that's unlikely happening anywhere. Still a good idea to make sure if you're using this library/headers.
