After waiting for pelican and server to come up, if either one has died then give a more helpful message and clean up. Previously did not check for this, so script informed user that everything was running even if one or both parts failed for whatever reason. This is meant to provide a little more user-friendliness in those cases where user has a develop_server.sh in project directory but forgot to (re)install pelican, activate relevant virtualenv, etc. as well as other unforeseen situations where one of the processes does not start.
