IasDialog doesn't allow injection of locals

[joswhite]

To fix this issue, instantiate the new dialog controller using:

let locals = options.locals || {};
locals.$scope = scope;

// Instantiate controller if provided
if (options.controller) {
    this.dialogController = this.$controller(options.controller, locals);
}

// Compile template
this.loadTemplate(options)
    .then((template) => {
    self.compiledDialogElement = self.$compile(template)(locals.$scope);

// Insert element into DOM
element(self.$document.find('body')).append(self.compiledDialogElement);
});

We also need to add an example of using this to the documentation site:

openTemplateUrlCustomDialog = function() {
    IasDialogService
        .open({
            controller: MyDialogController,
            templateUrl: './my-dialog.template.html',
            locals: {foo: 'bar'}
        });
};
