Upgrade to ngrx@4.1.1

[schacki]

I have problems using store-log-monitor with angular@5 and ngrx@4.1.1.
Are there any plans to upgrade?

The company I work for won't let us install Chrome Extensions for security reasons, so if I want to use DevTools this is my best option.
I ended up fixing the errors and moving the dependency on @ngrx/core to @ngrx/store.
Is a PR with that something you would be interested on?

The maintainers of this repo dont look like to be interested on keeping the code.
Why dont you guys give this a try?
