This commit prepares the frontend code to be consumed by webpack.
It is a hack: In theory, modules should be declaring and importing the
modules they depend on and the globals they expose directly.
However, that requires significant per-module work, which we don't
really want to block moving our toolchain to webpack on.
So we expose the modules by setting window.varName = varName; as
needed in the js files.
This makes sure that CSRF token is available while initializing
Socket, irrespective of the order of execution of deferred callbacks
after document becomes ready.
This is part of #9416.
This is an issue where in jQuery v3 the result of outerHeight on a node
that doesn’t exist is now “undefined” rather than “null”, which means
it will no longer cast to a Number but rather NaN. For this, we create
the safeOuterHeight and safeOuterWidth functions to safely return a
result (or 0).
This is a better solution than manually going to each instance and
ORing it with 0 for type safety.

In this we fix the positioning of the loading spinner on the home page
when its loaded for the first time. First time here does not mean first
time use but means first time of a new session.
iOS doesn’t seem to play nice with the web socket library we are using
them, so disable use of websockets for sending messages until we can
fix that.
Fixes#2306.
We only use zxcvbn in the main webapp for checking the user's password
in the change password form. Since zxcvbn is a very large javascript
library (~700KB), loading it asynchronously only when a user is trying
to change their password results in a significant performance
improvement for loading the Zulip webapp on a slow network.
Fixes#263.
