Description of your pull request and other information

fixes #16398
Tou.tv was redesign with react and the login url was moved into JS. The code was not able to find the clientID needed.
My fix browses through the app.js file to extract the clientID needed for the login form.

Hey kudos for the fix !

I am new as of today to youtube-dl, but it worked flawlessly after doing a checkout of your toutv_account branch.

I tried running this branch and while it seems I can login, there is an error afterwards.

Weird, i just tried it and it worked. Looked like the server send a timeout error. Maybe give it another go. I notice tou.tv seems to have server issues recently.

Bonne chance!

Franchement, j'aurais pu essayer deux fois... ça fonctionne bien, merci! =)
