Localize the CLI

[mrbiggred]

Currently the messages displayed by the Freshli-CLI are not localized but are just hard coded English strings. This case is to localize any messages displayed by the CLI including help. The command line arguments won't be localized.

This issue only covers the CLI. If any messages are displayed from Lib they will either still be displayed unfocalized (i.e. in English) or the CLI will have to override the message.

Also this issue only covers localizing the current English messages. New cases will be created to actually adding new languages.

Some documentation on how to localize .NET applications can be found here
