Secret-Nuke playerlimit raised

The player limit was originally fifteen, which, as a TG coder helpfully inputted, there were a minimum of ten players and five nuke agents.

That's way to damn low.

This will/should raise the limit to twenty five, allowing for twenty crew members instead. More manageable and more likely to actually have the necessary heads and security positions filled out. If problem persists, it can be raised to thirty, though that will make nuke very rare indeed given it's X amount of readied people. We'll see.

As aside, this is only for secret nuke. Normal nuke is six, but you have to consciously vote for that so who cares.
