Provide a configuration option to limit the number of actions logged

[jcharry]

Issue: The actions logger panel accumulates actions for a story endlessly. After a while, this creates quite a bit of lag. You can hit the clear button to clear out the logger and performance improves again, but it'd be nice to have a configuration hook to set a hard upper bound on the number of actions that should be logged.

What I did

Added a configuration option called limit to the configureActions call.

A default limit could probably be added to configureActions, not sure what the default value should be though.

I've added @Hypnosphi as reviewer, does the PR also need to include an example in the official-storybook?

[danielduan]

I think we should set a sensible default for all users while we're making this change. This seems like an obvious optimization we can make on behalf of all users.

does 50 sound like a good number?

Yeah, that wouldn't hurt

Makes sense to me

[jcharry]

Sure, I'll make those additions.

@jcharry can you fix the failing test here?

yarn bootstrap --core and then yarn test --core --update

[jcharry]

@danielduan done!

[Hypnosphi]

Please add a usage example to examples/official-storybook

[jcharry]

@Hypnosphi Okay, added an example.
EDIT: Oops, now there are some conflicts. Let me resolve those.

[jcharry]

Rebased and should be good to go now.
