Enabled widgets with invalid positions should raise an error

[senorprogrammer]

What's the problem?

If the position data is malformatted a widget will silently fail to show up:

    cmdrunner:
        args: []
        cmd: "uptime"
        enabled: true
        position:
        top: 1
        left: 9
        height: 1
        width: 4
        refreshInterval: 300

How did you expect it to behave?

This is effectively the same as height: 0; width: 0 which should be treated as invalid. If a widget is enabled it must have a height/width minimum of 1.

If the widget is enabled and if the position is invalid, then raise an error and do not load.
