Accelerator key support for menu items?

[lawson89]

Currently doing this a lot and would rather do accelerator='VK_F' in the xml. Happy to submit a PR to add this if you are busy

        var acceleratorKey = Toolkit.getDefaultToolkit().getMenuShortcutKeyMaskEx();
        findItem.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_F, acceleratorKey));

Seems reasonable. I will take a look.

Done. Will be released with v3.5.2.
