Pause orders based on price (limit orders)

[otmooon]

Is your feature request related to a problem? Please describe.
Users may want to limit their exposure to bitcoin/fiat price volatility. For example, a seller may no longer want to sell when the price drops below a certain point and a buyer may no longer want to buy when the price rises above a certain point.

Describe the solution you'd like
In order creation, allow the maker to set a price limit upon which the order state changes from Public to Paused.

If the maker is a seller, then the limit is a lower bound; if the price falls below this limit, the order is paused.
If the maker is a buyer, then the limit is an upper bound; if the price rises above this limit, the order is paused.

If the price returns to a level that is acceptable to the user, then they can choose to unpause the order.
