Revamp the library views

[TheBlackParrot]

• Drop controls on the main pages
• Create a panel that slides out from the right, giving information for a selected track, and controls to manage it (queue/unqueue, delete, edit info (eventually), etc.).
  • This would be a lot easier to deal with in the future, and we can make the control buttons more descriptive.
  • It's also less clunky, and allows the current gradient overflow to be managed much better. This would fix the guest issue with it, as both registered members/guests would see the same width.
• Apply this to all views, giving the same panel to each section.

for reference, if we do this, we can close https://github.com/SwooshyCueb/strimmer/issues/98, https://github.com/SwooshyCueb/strimmer/issues/97, https://github.com/SwooshyCueb/strimmer/issues/94 (partially), and https://github.com/SwooshyCueb/strimmer/issues/89
