Add game option for textual order input.

[zond]

This would do a few things:

• Turn off the order options structure being sent to the client.
• Turn off error response codes for invalid orders.
• Refrain from sending orders for unresolved phases to clients.

This would force games to not validate orders, and give players leeway for breaking orders.

@tttppp, @JorenC what do you guys think?
