Added love.window.showMessageBox.

Browse Source 
It has two variants: showMessageBox(type, title, message [, attachtowindow=true]), and showMessageBox(type, title, message, buttons [, attachtowindow=true]). The former shows a simple message box with a single OK button, and the latter displays several buttons. The buttons argument is an array of button names.

The second variant returns the index of the pressed button, or 0 if the message box was closed some other way. showMessageBox will block until the message box is closed (and it can't be called on a separate thread.)
