fully implemented server application (windows) 22102013

In this commit we have first prototype version of an fully implemented
server application (Windows Only), with all possible handlers
(stop/termination_handler, pause, resume, wait for termination request)

This has same functionality of old version (beta 3), but now using
aspects.

The main changes are on:

app.hpp
sever_application.hpp

example: simple_server_application.cpp

Now we also have a way to customize the signals/handlers on common app,
refer to:

my_own_termination_handler.cpp

Many other modifications and fix were made.
