Changed maybeUnstress(word) so that it reads from maybestressed.txt and unstressed.txt. In the former case it adds an unstressed option if only a stressed one exists, and a stressed option for the word if only an unstressed one exists. If a word is not in maybestressed and is unstressed, it is forced to be unstressed. In both cases unstressed also means functionword=True. This is all meant for monosyllabs only.
