The changes are mostly done via `xo --fix`; the other changes are
either trivial or disabling new linter rules that we plan to address
in future commits.
The changes here are mostly straightforward; the one exception is
removing a zulipdev.org hack.
We disable some lint rules we'll want to address later (E.g. we want
to switch to using async/await rather than .then()). But those are
out of scope for this commit.
Moves the social login to browser since there
was no way to verify the authencity of the
auth process for a custom server and to
prevent phishing attacks.
Fixes#849.
