Total score starts at record score

Improved version checks for demo file lists

See merge request !2095

No longer relies on the demoversion global variable (which was incorrect for a couple instances, like ghosts), now we pass the version to the file list functions. Also don't set any demo global variables when checking a demo for valid files before playback. Also also, exit said file check function asap if its a title demo instead of doing it after we've already opened the file.

Means there's actually feedback for how much score you got in the current level.
