feature: Allow sorting by any column

This feature allows any column to be sortable.

This also adds:
- Inverting sort for current column with `I`
- Invoking a sort widget with `s` or `F6`.  Close with same key or esc.

And:
- A bugfix in regards the basic menu and battery widget
- A lot of refactoring
