Merge branch 'dev' of https://github.com/eardish/ephect-dataobjects into dev
removed one of the references to isRouteable() so that it only asks for the
routeable status from the RouteBlock itself.  (the routeblock is the only
object in Request that is responsible for whether or not it is ready to be
dispatched).
removed last reference to routeable in Request -- should all be through
the RouteBlock now.
