create tf.app module

[Yuri Malheiros]

This module provides functions to get important objects, for example, DocumentManager, PreferencesManager and MainWindow.

These objects will be created and assigned to a module variable. Then to get these objects you only need to do:

import tf.app
tf.app.some_object

[Yuri Malheiros (yurimalheiros)]

It's only a module with some objects. Yes, there are a blueprint called tf-api.
