Ktlint: Default continuation indent for Android should be 8 not 4

[MyDogTom]

This commit changes continuation indent from 8 to 4.
According to Android Kotlin style guide it should be 8.
I guess confusion comes from https://github.com/android/kotlin-guides/issues/37. But that issue is about usage of "indent" instead of "continuation indent" for parameter list. Not about changing the size of continuation indent.

@MyDogTom right. Thanks for pointing it out.

I think this was recently changed to be 4.

They wanted to have the fields in classes aligned with everything else and hence they made that change. https://github.com/android/kotlin-guides/issues/37

@vanniktech see latest https://github.com/android/kotlin-guides/blob/master/style.md#continuation-indent. @MyDogTom is right. Android Kotlin Style Guide prescribes +8 continuation indentation (+4 for parameters).

"Android Kotlin Style Guide prescribes +8 continuation indentation (+4 for parameters)."

Is there a way to specify that in IntelliJ / Android Studio? The "continuation indent" setting seems to control both.
