Ww3 feature/true false issue

This feature changes the way that perl dancer sends booleans.  Now the client-side code has javascript true/false instead of 1/0.  

To test, select any boolean (Settings and in Problem Sets Detail, Problem Sets Manager).   Check if visible or enable_reduced_scoring shows up or setting is saved correctly.  The enable_reduced_scoring will appear in the problem set sidebar, however most settings only appear in the course's simple.conf.
