Add filterBreadcrumbActions option

[bjudson]

filterBreadcrumbActions is a function that returns true if an action should be added to the breadcrumbs.

The rationale for this is that some Redux apps use some actions internally to trigger state changes that are both prolific and not directly connected to user behavior. They can overwhelm the logs and have essentially no value for debugging purposes.

How about instead of an array of types, we allow the user to supply a filterBreadcrumbActions function?

Also, I think the action should still be set as the lastAction even if it has been filtered out. Could you add a test to confirm that?

Thanks for the PR, I think this will be a great improvement.

@captbaritone Good idea. Updated PR with your suggestion. The test I added now confirms that the filtered action was omitted from breadcrumbs, but still included in lastAction. Thanks!

[captbaritone]

Looks good! I'll cut a point release.

[bjudson]

Thanks for the quick feedback & merge! This is definitely going to improve our debugging process.

[captbaritone]

Okay. Should be available in v1.1.0

Thanks again for your work on this!
