Patch 1.4.4! New Music and QoL Changes

Minor update, weapon selection numbers for upgrades are now colored to better indicate which weapon you are applying the upgrade to, new music has been added to the harder stages (the blue and red difficulties has other music than the green one), there is now also a volume slider in the main menu, for now it only applies to the background music cause I want to keep the other audio on a separate volume (this means if you for example want louder music and less loud other sound effects you can lower the game window volume but increase the background volume, this also goes the other way around). There may also be some other minor changes im forgetting about
