Fix scrollbar + sizegrip issue causing view expansion.

Removed the style for `QWidget:disabled:hover`, which causes the issue, and seemingly has no negative consequences since the default background color is still `^background^` without it.

Closes #54.

 - Triangular QTabBars do not have hover events for non-selected widgets.
 - Custom padding for triangular QTabBars on the bottom is ignored. All other tab positions work.
 - `QDial` cannot be customized via a stylesheet, which is a known bug in [QTBUG-1160](https://bugreports.qt.io/browse/QTBUG-1160). An example of how to style a `QDial` is available in [dial.py](/example/dial.py). This works out-of-the-box, and can be a drop-in replacement for `QDial`.
-- The size grips in a `QColumnView` will cause the column to auto-resize on a hover event with a stylesheet set. It's recommended to set `setResizeGripsVisible` to `false` until this is fixed.
