Updated service generator to have proper type hinting and more friendly
variable names.
Changed result and response classes to not have constructors or setters.
Changed setters and getters to camelized versions of the variable name
to get rid of underscores in method names.
Added sfInflector::camelize dependancy in constructors for runtime
camelization.  This needs to be removed and a different runtime
camelization method added but works for my current requirements.
