an attribute “not sure” and a note place for “Lemmatize this reading” function

[anahitsafaryan]

e.g. when I am not sure if I should choose անցանելոց-անցանելոյ I choose the one I think is more probable and leave a note, but that reading appears not in red, but let’s say in yellow, so that later it’s easier to find the lemmatised readings that may be wrong
