In CLI mode, order of modules is wrong. pretokenise=>acorn parse errors

As mentioned at http://forum.espruino.com/conversations/367900/#comment16179710

Basically the CLI loads the modules in the order that they are in the directory. There are actually specific orders required though - eg https://github.com/espruino/EspruinoWebIDE/blob/master/index.html#L220

So we should probably have a 'sortorder' in the module declaration, and then they can be sorted before init is called
