Add command line parameter to force language

[szszszsz]

Add --language CLI parameter for cases where automatic language detection would not return expected results (eg. where user has different language/locale on OS than he wants to use in application).

What are the available options/languages?

[szszszsz]

Available options are listed in i18n/directory - all ts/qm pairs without the nitrokey_ prefix. Currently these are:

• none - translation file will be selected automatically (default)
• arabic - recently added translation for Arabic (should be selected automatically on systems with Arabic locale set)
• de_DE - German
• en - English (second default if there could be no language file selected automatically)

Translation files are selected automatically through locale code (like de_DE, en_GB etc.) or by language. If OS has locale other than language user wants to use, he has to run application once with desired language, eg.:
nitrokey-app.exe --language arabic
The choice will be stored in application's settings file and used on subsequent application runs (whether it is run from a terminal or not). To clear it user has to use --language switch without a param:
nitrokey-app.exe --language
Similar information regarding language switching could be obtained by running:
nitrokey-app.exe --help
