Chronicles translation split

[GeorgeK1ng]

1. Added support for chronicles.json in main translation and correctly list Game, Maps, Campaigns, Chronicles translation progress
2. Improved mod translation details with real mod name, mod type and sorting

How it will looks can be seen here: https://github.com/GeorgeK1ng/vcmi-translation-status but in my main branch is linked to beta branch instead of develop.

Can you harmonize all translation to use chronicles.json (instead of other named jsons) then I think we could merge.

I'm working currently on another solution, which works for both methods. Just latest test needs to be done and I update PY code in this PR.

Done, you can see on my main repo fullfilled Czech, German etc.. :)
