Upgrading to Qt5

After some time in silence, I'm happy to inform that most of our products are getting upgraded to the new Qt5 framework. This is the latest version of the development engine for all our applications, therefore this port is a natural step.

This port will make possible to create a native version of our mobile applications (mobiFinance and Safebox) to the world of Android and iPhone.

This effort is a leverage of the new support of Qt5 in these two new platforms.
