1. Provide "permission states" in custom strategy callback
2. Provide "permissions states" in event emitters (authorized and unauthorized)

@AlexKhymenko Thank you, can you give me write access to the repository or the conflict files so I can resolve conflicts ?

[AlexKhymenko]

@yd021976 Actually there is a message that 'this conflicts are too complex to resolve in the web editor' Can You merge master to Your branch?

[yd021976]

@AlexKhymenko Hi, i've fixed conflicts. But seems that as I modified the project structure to be Angular 7 compliant, it breaks your travis CI build (actually, package.json has been moved to "./application" instead of being in ./ before ==> I think there is a lot of other changes in my PR that will break Travis CI.

[yd021976]

@AlexKhymenko Hi again :-) I confirm that the new project structure definitively break your Travis CI.
When you have time can you update travis CI to validate my PR ?

Thank you !

[yd021976]

@AlexKhymenko , I've made some changes in package.json so that Travis CI should run with success. Unfortunately, Angular V6/7 needs Node js >= v8.9

Could you please change the Travis CI config with a required node version compatible with angular >= V6 ? (i.e Node V8.9)

Thank you

@AlexKhymenko oupss... Sorry for my requests about Travis CI, I've just learn that I can customize the depedencies in project file ".travis.yml"

Now my last commit have passed all checks successfully :-)
