Fixed files json updated to 4.2

Hello,
Just wanted to point out that, on my repository i've fixed and updated all the jsons in data to be compatible with Final Fantasy XIV patch 4.2

[https://github.com/easly1989/ffxiv_act_dfassist/tree/master/data](https://github.com/easly1989/ffxiv_act_dfassist/tree/master/data)

You may include those updated files to your project as well.

Just one thing.

For all the language i've used the English names for the dungeons (and comments).
If you have/can find the source for the correct translation feel free to modify them.

best regards,
Carlo
