Add a way to ignore certain errors in crash overlay

[gaearon]

There are cases when it’s impossible to catch an error.
For example:

setTimeout(() => {
  throw new Error('Boom');
});

This may happen inside a third party library that user has no access to. We should have some way to ignore errors by message (at least if localStorage is available for the blacklist).

When you say ignore, do you mean a hotkey to "ignore this error in the future"? Or a file/package.json entry to ignore regex matches?

Should we just ignore errors that have no stack traces to our application? I think that makes the most sense -- or at least show them up as if they're a warning (when we make the warning overlay, which is more like a warning toaster).

This sounds very reasonable. Can we do this?

I don't see why not. Let me play with it.

This was added in #2128

Looks like feature described in the OP ("We should have some way to ignore errors by message") didn't get implemented. I'd still like that feature. Should I open a new issue, or could we just reopen this one?
