Double click on the Minimize All Windows would not show the desktop two times

It would instead show it three times,

Showing the desktop button could be edited so every time we click, we toggle between the windows and the desktop

Every time we click it, there would be a event fired and this function called.

wincmd_button_clicked

If we click the button slowly, it would work well.
However, if we double click it, it would fire an GDK_2BUTTON_PRESS and GDK_3BUTTON_PRESS

So I suggest we only focus on GDK_BUTTON_PRESS
