Add new language to Invisible Man XRay

Here are the instructions for adding a new language to the app

Invisible Man XRay supports various languages.

By doing these steps you can add your language to the app:

Clone a copy of the repository:

git clone "https://github.com/InvisibleManVPN/InvisibleMan-XRayClient.git"

Switch to the develop branch:
```
git checkout develop
```
Go to the InvisibleMan-XRay/Assets/Localization and duplicate the en-US.xaml.
Rename the duplicated file to your language.
Now try to translate all the terms into your language.

Go to the InvisibleMan-XRay/Windows/SettingsWindow/SettingsWindow.xaml.cs and add your language to the Languages dictionary:

private static readonly Dictionary<string, string> Languages = new Dictionary<string, string>() {
    { "en-US", "English" },
    { "xx-XX", "Example" }  // Your language
};

Test the app and push your changes as a pull request.
