RoundedTB does not re-apply/refresh rounding when display changes resolution

[johnnaaron]

Currently, RoundedTB stops working and reverts to the default taskbar when there is a display or resolution change, rather than refreshing its state.

When RoundedTB is 'shown' via right-click in the system tray, it starts working again.

I believe this currently affects users of virtual machines, borderless/windowed/fullscreen games, and those of us who need to change scaling/resolution for compatibility reasons.

Thank you :)
