Commit: Chris Feng <address@hidden>

    Add a command to interactively move X window to the current workspace
    
    * exwm-workspace.el (exwm-workspace-move-window): Hide buffer on the 
original
      Emacs window when moving an X window to the current workspace.
    * exwm-workspace.el: New function exwm-workspace-switch-to-window for
      interactively moving an X window on another workspace to the current one.
