Add ability to reload the ingame overlay via keybind.

[qt715]

Description

As the title states, I request implementation of a keybind to reload the in-game overlays.

Why?

While it is not bad to navigate to the system tray, right-click on the tosu icon, and press "reload overlays", it is quite tedious when I have to do this every time I make a code change to one of my overlays.

This would be cool, but we can also fix the OP issue by having overlays reload more frequently.

or add button to reload any overlay in ingame-overlay itself
