[feature requests] implement Action Management in QElectroTech.

In small applications it is easy to do action management manually but as applications get bigger, its useful an it saves time to use a proper action management system. The action manager allows actions and shortcuts to be linked with contexts and to change their behavior depending on the active contexts. An command editor widget is provided to allow users to change their application wide shortcut settings, or to export and import previous sessions.
