A couple of fixes . . . .

-- the first is a generalization of last week's commit to prevent which-Q-word from being classified as a determiner

-- the other two commits improve the realization of the imperative subject which was getting a 'null' instance that was throwing r2l.  Now it gets a uuid and a name, however its instance-name is "left-wall', however its concept is "you"; its a left-wall which is a "you."  I guess that's an appropriate imperative subject? It works.  I couldn't change the left-wall into a you-instance without totally de-railing relex and r2l.  
please add example sentence that needs the JQ link
