Small but important stuff

- More player count fixes for votes.
- Fixed Shine.GetAllPlayers() (which relied on Shared.GetEntitiesWithClassname) returning a table with more player objects than there are players on the server when players were dead and spectating. I'm pretty sure this was causing the rare team imbalances when shuffling.
- Added two more win condition options to the round limiter plugin, the team with the most RTs at the end, and the team that collected the most resources over the round.
