Subject: [PATCH] Fix bug preventing a user from being able to "unselect" a
 word while judging

Previously, the selection was accidentally "sticky" unless the player
went on to group a word with another. So if the user accidentally
clicked a word there was no way to unselect it without maging a bogus
grouping and then undoing that.
