Big changes in code of clients, screens and widgets.

- Moved and altered code to create, destroy and manipulate clients, screens
  and widgets in an OO-like manner.
- Moved command execution code to a commands directory, splitting commands to
  what subject they are concerned.
- Menus are temporary disabled while working on new menu structure.
