Typescript typing bugs

BryntumWidgetAdapterRegister is missing a declaration

BryntumWidgetAdapter's declaration is blank

TaskModelConfig only has one field, listeners

This may not be a bug, but it would still be convenient to export the Config types, e.g. TaskModelConfig + ProjectModelConfig

MessageDialog.confirm says it is returning void, though it should return a Promise based on its implementation. Type def:

export class MessageDialog extends Popup {
    constructor(config?: Partial<MessageDialogConfig>);
    static confirm(options: object): void;
} 

Implementation returns:

return me.promise = new Promise(resolve => {
  me.resolve = resolve;
});

yesButton, noButton, and cancelButton should also probably be added to the MessageDialog type.
