Applying MaaMacGUI i18n translations

[RieLCho]

Before raising the issue...

• I filled in a short, clear title so that developers could quickly identify the general problem when going through the issue list. Instead of "Some suggestions", "Stuck", etc.
• I'm probably sure this is a new feature/suggestion and not a bug encountered (please attach logs if you're not sure)

The problems you have encountered?

First of all, thanks for contributing macOS client. I'm using this client very well, but most of foreign users would might need a i18n translations.

Any good ideas?

I guess we should remove those hardcoded strings and use NSLocalizedString
