A get-out clause for infinite loops when generating variables #713

If generating variables takes ages, the question editor can appear to lock up when you load it. Maybe we should wait until first draw before generating variables, and then have something to catch it taking too long, and abort and show an error message.

…page was open, don't autocalculate When the question editor loads, it sets a local storage key. Once a set of variables has been generated, that key is removed. If the key is still set when the page loads, then variable generation mustn't have finished last time the editor was open at this question, so don't automatically generate variable values. This gives authors an opportunity to fix questions with infinite loops somewhere in a variable's definition. This doesn't completely solve #713, but makes it possible to get yourself out of the situation where a set of variables can't be generated.
