Emscripten documents that preRun should be an array of functions, but also accepts setting it to a single function. qtloader.js was accidentally using this feature, which works as long as qtloader is the single user, but breaks if other code expects an array. A typical error in this case is: "Module.preRun.push is not a function" Fix this by creating and maintaining preRun as an array.
