French dictionary: fix for looking up feminine/plurals

A small fix has been applied to the site's French dictionary to fix a bug when looking up French feminine and plural forms.

Occasionally, when looking up a word ending in -e or -s, this word would mistakenly be assumed to be the feminine or plural of another word. For example, baie was taken to be the feminine of bai, when in reality it is much more likely that the user was looking up the word baie ("bay", "berry").
