* add button to About box to copy Joplin's information to the clipboard
On certain OS it is not possible to copy the text in the About window.
This change allows to copy that info to the Clipboard.
Due to some shortfalls in Electron, it is not possible to set `defaultId` and `cancelId` to 0.
(Actually one can set them to 0, but the result is not what one would expect.)
Thus I had to move the default `OK` button to the left.
I also added a hack to position the `OK` button approximately in the middle of the dialog box (if the copyLabel is not longer than 14 characters).
* remove hack to position button
* add a new bridge function showMessageBox
The function returns the index of the clicked button.
