New action, "Play Folder"

[GeekyEggo]

Purpose

This issue aims to centralize the discussion of adding a new action that allows users to play audio from a folder.

Overview

It should be possible, from a new action, to select a folder, and then play audio from that folder when pressing the action. The action should provide a lot of the functionality seen within the existing "Play Audio" action, i.e. device selection and playback action.

Options

• [ ] Playback Device
  • Should include "Default" and "Default (Communications)"
  • Show list all other playback devices.
• [ ] Folder
  • The folder that contains the audio files.
• [ ] Files
  • [ ] All(default)
  • [ ] First (fulfils #38)
  • [ ] Last
• [ ] Order
  • [ ] Date created
  • [ ] Date modified
  • [ ] File name (default)
  • [ ] Random
  • [ ] Title (ID3 tag)
  • [ ] Track Order (ID3 tag)
• [ ] Action
  • Play / Next (default)
  • Play / Stop
  • Play All / Stop ¹
  • Loop / Stop
  • Loop All / Stop ¹
  • Loop All / Stop (Reset) ¹

¹ Only available when the files selection is "All"

Requirements

• [ ] The action must be able to play audio similar to the "Play Audio" action.
• [ ] The action must automatically detect file changes for the selected folder.
• [ ] The action must support the following file formats
  • [ ] MP3, *.mp3, *.mpga
  • [ ] OGG, *.oga, *.ogg, *.opus
