Music update

The music player and other features hadn't been touched in the prestige remaster so I thought I would give them a quick update to go along with the new update, so welcome to the music update, you can see a list of updates and bug fixes below:

-------------Music update-------------

• Added the ability to play more custom music such as tbbt op, Brooklyn 99 op and more!

• Added more achievements to earn

• Fixed the leader board crashing when uploading your score

• Secret songs now get saved to the music player

----------------Bug fix 1----------------

• Fixed sus generators just failing randomly (and at startup on web)

• Fixed the suses multiplying themselves by 10x when buying something

• Fixed the upgrades not actually costing you anything

• Updated the rebirth text so you can see how many you have (thx Cal)

• Fixed the spent suses not tracking at all.
