Demos/CatDog: Refactor the main states

Browse source 
CatDog's state was previously handled by a bunch of booleans that all
needed to be in sync pretty accurately, but some of these are exclusive
(like alerted and sleeping). This commit introduces a simple enum for
the main states of CatDog which exclude the roaming and direction
states. The main state determines the standing image of CatDog and will
have further effects in the future.
