ctools requirement

Hi - I followed the video howto and was getting blank, half-formatted drealty listing displays when trying to view a drealty listing, until i noticed it was trying to use ctools for the css or something.

In any case, I enabled the ctools module and the drealty listing displays fine.

Not sure if this is a real requirement, but if you are mapping to cck, i think it is a requirement.

Thanks for an excellent module!
