A detailed pause function to pause a match when needed.

When /pause is executed...

• Save player inventory
• Freeze player in current position
• Save hunger/health
• Disallow the placement/removal of blocks
• Disallow eating & drinking
• Disallow modifying blocks such as chests and furnaces
• Set all players to creative, removing mob aggro.

When /unpause is executed...

• 5 second countdown
• Restore player inventory (Done at last second of countdown)
• Restore previous hunger/health stats (Done at last second of countdown)
• Set players to survival (Done at last second of countdown)

This could be especially useful for tournament matches if there are server issues, or if a player has a connection issue. Not sure if all of this is possible or not, but definitely something to consider. It could save RMCT tournaments from many issues.
