Locations of special menu items

[nis]

Hi.

Eto.Forms' MenuBar has some special items.
(ApplicationItems, QuitItem, AboutItem...)

Currently they seem to be located in fixed parent-menu.
(ApplicationItems and QuitItems are placed in "File",
AboutItem is placed in "Help")

I want Eto applications internationalized,
so English words such as "File" or "Help" must also be localized.
But in my case...

## Sample code

Menu = new MenuBar
{
Items =
{
new ButtonMenuItem { Text = "&Expediente", Items = { clickMe } },
},
ApplicationItems =
{
new ButtonMenuItem { Text = "&Preferences..." },
},
QuitItem = quitCommand,
AboutItem = aboutCommand
};

## Result

Windows(WPF) : "File" and "Help" are generated along with "Expediente".
Linux(GTK+3) : Launch failed

## Requirement

I want Eto.Forms allow localized menu items,
maintaining special items' functionalities.

## Exception on linux

Hi Jirou,

There's no way to internationalize the special item menu headers at this point, which will need some extra api to accomplish.

Please file an issue on GitHub so I can schedule this in the roadmap.

Cheers!

Curtis.

Hi Curtis,

I recently saw Eto's code and found it possible now (at least 2.3).

```cs
MenuBar Menu;
// 'Menu' constructor
Menu.ApplicationMenu.Text = "&Expediente";
Menu.HelpMenu.Text = "&Ayuda";
```

This worked on Windows(WPF) and Linux(GTK#3).

Thanks, curtis!

Awesome!  That's a great way to do that.
