Special case quotes at start and end of words

Single quote at start of word is not considered a part of a
word any more.
Single quote at the end of a word now behave like capitalization:
lookup in the dictionary is done *disregarding* a final quote,
and it is forcefully added back into the suggestions afterwards.
