v0.8.5

Changelog:

• Added a feature to the Spotify visualizer that sets the default palette to use the album art colors. The palette will continue to update each time the album art changes unless the palette is changed manually by the user.
• Fixed a bug that prevented setting up devices using the "Add New Device" button in the device changer.
• Fixed a bug that caused the user to set up their device each time the app opens. This only applies if the user set up their device using the "Add New Device" button in the device changer.
• Changed window UI buttons to (hopefully) allow for them to appear properly on all platforms, namely Linux. Let me know if they don't show up properly on this release.
