Forgot to change some values.

Added Tino Mori, Epitaph of Seikilos, and Magna Mater from civ 6.

Made it so that Greek music will be heard even if you're Roman. I didn't like that it would be lost since I think there are some good songs there.

Turned down some music, and increased the chance of the music playing from 2 to 4 for most of the songs.
