I want to allow users to select whatever language they want. So I'd like to ask for a new syntax of the localize command:
```
text localize language
// or
localize [text, language]
```
both `text` and `language` are strings. `language` is either one of the supported languages in `stringtable.xml` (English, German, Czech, etc) or additionally, `"System"` which just does what the default syntax does (uses the selected game language)
