Add localization

[TetraTheta]

I am currently writing this issue using a translator. Please understand if you see awkward or inappropriate expressions.

The Division 2 is served in several languages. However, this wonderful tool is currently only available in English.
According to the Steam store page, The Division 2 is served in 14 languages, including English.

I suggest adding a drop-down list button to switch user languages on the main screen of this tool.

From a technical standpoint, the language you choose is stored in the Local DB, and each language should be loaded when necessary with an independent language-specific JSON file.
When using independent language-specific JSON files, the participation of contributors in each language can be recorded as individual commits.

Once again, thank you for making this wonderful tool!

We are working on a V2 that will have localization. We may look into doing this for V1 but for the moment it is not planned.
