Add guide for old Winamp look for Audacity

[SolsticeSpectrum]

This adds even more nostalgia

All that has to be done is putting this file
https://skins.webamp.org/skin/5e4f10275dcb1fb211d4a8b4f1bda236/base-2.91.wsz/
or this file
https://www.gnome-look.org/p/1008329/

I would call them something like winamp-classic.wsz and audacious-classic.wsz when adding them to the repository

to .local/share/audacious/Skins (create it if doesn't exist)
after that it can be selected in settings->appearance

The first one is classic winamp all the way, the second keeps the name audacious in the title and the audacious icon.

I 100% agree but I don't have the time to write this up. If you write up a guide I'll accept the pull request.

Sure but you will have to explain to me where should I put it, should I make a new folder in the root?

Fork the repo, edit INSTALL.md, making sure you update the table of contents and match formatting, etc, and add the screenshots to the 'Screenshots' folder.
