Game Updated - general fixes and music

Hi! This is the first proper update.
There were smaller updates that fixed some minor bugs that bothered me a lot, but I didn't make a post for those. Mostly because I didn't know how many little fixes I would add. 

Either way, what's new:

1. Added music and the relevant settings
2. Prettied up the sprites for some characters (still placeholder sprites, but they generally align with what the final design will be)
3. More bug fixes (I don't remember how many)
4. Credits button (it's there to look pretty)
5. Adjusted the tutorial (you can now skip the spin set bit)
6. Adjusted the available resolutions
7. Adjusted some sprites where it looked like color spilled out of the lines
8. Buttons get pressed like buttons instead of accepting their existence in begrudging immovability
9. Adjusted the dialogue in some places
10. Probably some more small tweaks I forgot about

If you want to listen to the soundtrack, keep in mind that I found it on a royalty free website and the producer doesn't know me whatsoever. You can find it on: https://freesound.org/people/LittleRobotSoundFactory/ under "Thoughtful Music Loops Library" and "Victory War & Battle Music Loops Library".  It's good.
