Kyodai Editor > Restart button on the toolbar

As it took me around 10 years to discover this contextual menu, it's better on the toolbar..

Almost as simple as replace the function behind .

and play a bit with the icon.

To be perfect:

- The new button shall be disabled when we are not in game (like the other ones) and translated.

First one is the trickier but not impossible with upcoming changes. TBA
