Use consistent naming & constructors in custom views

[nielsvanvelzen]

We have quite a bit custom views. A lot of them, unfortunately, still written in Java. This PR only focusses on the Kotlin based views.

Changes

• Use consistent naming for custom views
  • End with "Layout" for layouting (FadeViewSwitcherLayout)
  • End with "Preference" for preferences
  • End with "View" for all other views
• Always use this particular constructor, with defStyleRes omitted if the extended view does not support it (like AppCompatTextView)

   class MyAwesomeCustomView @JvmOverloads constructor(
  	context: Context,
  	attrs: AttributeSet? = null,
  	defStyleAttr: Int = 0,
  	defStyleRes: Int = 0,
  ) : View(context, attrs, defStyleAttr, defStyleRes)
