Fixes

- Add a "Browse..." button to the plugin menu
- Remove the "Unload All" button from the plugin menu if there are no imported plugins to unload
- Add a new search filter: random:yes
- Resolution settings now affects the results screen assets
- Pixelate more assets with lowest resolution setting
- Fix loading error message not appearing sometimes
- Remove img.css from img assets, the background selectors have been moved to assets.js
- Separate the search logic from SongSelect to its own js file
- Load all image assets with crossorigin=anonymous, this could allow making assets low resolution or programatically taking screenshots at a later time
- If EditFunction in a plugin tries to edit something that is not a function, it will give a better error message
- Disallow search engine bots from indexing images and adding a translate link, which cannot load the game
