More reliable player count source
Should return 0 rather than nan

when there's nothing in the table.
Minor script error fixes
Fixed more player count errors

- Added "FriendlyFirePreGame" setting to determine whether friendly fire
should be enabled before a round has started.
- Map and shuffle votes now better inform the player why their vote
failed.
Added win conditions to the round limiter plugin

You can choose whether you want the team who scored the most points, had
the most RTs at the end, or collected the most team resources over the
round to win.
Clamp the win condition

In case anyone puts it out of range...
Consistency

I use localised versions elsewhere so I should here too.
No longer rely on Shared.GetEntitiesWithClassname

for getting all players. It adds extra players for dead spectating
players which messes up team swapping.
