Add MultitouchView

Solves #175

The messages are something I came up with just now so please feel free to edit them to something better.

Notes:
The window isn't resizable to avoid complexity as the user will only look at this probably once.
The visual design can be improved.

Todo:

• Actually show a demo
• Replace icon (could be improved)
• Fix SwitchWorkspace
• Calculate values better (Values are constant because window isn't resizable)
• Edit visual design
• Make available only when there is touchpad

Gonna need some UX inputs for how this will be handled I think.
