Fixes towards MP3s hanging the game on first playback * Fixed MP3s recaching 2 times sometimes in a row * Fixed cache size not being able to exceed 65k * Make MP3s skip the ID3 data immediately on cache, not on first playback. This makes loading a bit slower per-file, but makes it so we don't need to cache 400KB of useless data per MP3 * Increased amount of cached data for MP3s to satiate initial burst of data access by BASS (from 16K to 96k) This was preventing async load of the entire file Merged Pull Requests * Refactor sandbox hints * Remove angular-ui, jquery-ui, jquery-color
