support Overleaf v2

[d-higuchi]

overleaf v2 launched and this tool did not work.

Traceback (most recent call last):
 File "/overleaf-backup-tool/overleaf_backup.py", line 50, in <module>
   projects_info_list = overleaf_client.get_projects(status="all")

   projects_list.extend(proj_json["docs"])
KeyError: 'docs'

Hi @cl-lab-k, I bet this would require important modifications to the code, because Overleaf v2 doesn’t seem to offer an API like in v1.

I wrote a quick and dirty adaptation of @tbmihailov’s code that downloads .zip archives of your projects. It’s nowhere as complete as this project, but at least it offers a backup solutions.

I am trying to adapt it. The old API is still active. But they changed the strategy for assigning cookies and I am still figuring it out. @ArcturusB feel free to make a pull request if you figured this out.

@tbmihailov: I have a working login function that I can submit as a PR if you wish. :)
