Add full integration with the Connectivity Frameworkv0.9-beta

Fixes Issue #1867 "Download app not working".
Uses proxy classes to hook into the application framework,
solving almost any problem with missing connectivity features,
creating a connection that is fully managed by the framework itself.

Introduces a background service that performs all backend operations.

Cleans up code design, refining structure of classes and entities.

-*) turn backend engine into a service
-*) introduce support for EAP authentication (if possible at all)
+*) Design a better model for preferences using ContentProvider
+
+*) Control wpa_supplicant directly using documented sockets and commands:
+   this should be the preferred way of communicating with wpa_supplicant, 
+   allowing a fine-graned control over the authentication process
+   and giving access to asynchronous events about the connection status.
+   
+*) SQLite database for storing network details:
+   drop the current JSON/text-file model and build a more consistent, 
+   more secure way of storing data.
+
+*) Support wpa_supplicant in AP mode to create a Wi-Fi hotspot
+
+*) Support captive portals (e.g. "public" Wi-Fi systems or on-campus Wi-Fi):
+   (needs thorough research)
