Add rule for warning against electron.remote

Summary:
I don't think there's an easy way to do this based on types
which would be ideal ...

So instead I'm checking for

- Importing `remote` from `electron`.
- Accessing `electron.remote`.

You can still hack this by importing `electron`, saving
it to a differently named variable and accessing `remote` on it,
but this should cover all reasonable cases we see in real code.
