U319 - lotu juice

Valid fruit names like lotus would result in funny fruit juice names, eg
"lotu juice".  Looking at a long list of words ending in "us", the ones one
might reasonbly use for a fruit name were all singular, as were almost all
of the unreasonable words.  Changed the logic to prefer to leave "us" words
alone, except for 2 monster types that might be entered with "s" at the end.
Tengus is not correct, according to makeplural, but I put that in to be nice.
