Add "Play album from here" as default click option

[seadowg]

Work towards #535

This adds the album default option and also reworks how the action icon/title is determined so that it uses ClickContext instead of needing to pass the parent Album/Playlist around.

@formatBCE this is currently failing because adding a new DefaultClickAction means handling it in the Auto/Carplay parts of the app. I don't have a car with Android Auto (or any car for that matter), but I'm assuming I try out the UI that AutoLibrary deals with in an emulator?

You can use Android DHU emulator for Auto.

@formatBCE do you have a set of steps for actually getting to the library UI displayed using AutoLibrary? I've never used the Auto interface in my life so it's all a bit strange. Maybe I'm misinterpreting things and it only gets used for voice?

Nah, not just voice! :)
To test it without the car, you need to install Headless Unit (it's program that emulates Android Auto). Then you just launch it, connect your phone to computer via USB - and it shows you Auto interface emulated via Headless Unit (DHU).

Installation happening through Android SDK manager. Then you do something like
/Users/{your_user}/Library/Android/sdk/extras/google/auto/desktop-head-unit --usb
