Backbone view that "starts" the application
You should shorten this up


if (pub_req) {
    Page.flip('splash');
} else if (!token) {
    Page.flip('splash');
} else {
    this.loadViews(token);
}



by merging the first two if statements, like this

if (pub_req || !token) {
    Page.flip('splash');
} else {
    this.loadViews(token);
}


This evaluates in exactly the same order as your code did, but it is shorter.




// View like objects - inject DOM elements needed
var BodyInstance = new Body(document.body);
var ErrorHandlerInstance = new ErrorHandler(document.body);
var TitleAjaxInstance = new TitleAjax($A.el("#timer"));



You have declared these variables but then you don't use any of them, anywhere in the code that you have posted, I can only assume that you don't need these and that you should remove the dead code laying around in your code.
