Work-around to include scripts

"I've been using the eval of UrlFetchApp() for several months but it sometimes fails because of DNS errors and sometimes for no reason, so I'm really waiting for this feature.  In my base script, I just put a function (that I never call) that calls all the services I plan to use, so that the auth gets done properly at the beginning. Because I use addMenu to give the user access to the functionality, I have a placeholder x_someName function for each button - when the button is clicked x_someName() pulls in the required scripts and executes someName()."
