Cancel a pending order

[Catrya]

A user can cancel an order created by himself and with status pending sending a message to Mostro with the action cancel.

Then Mostro response to the user confirming the order was canceled.
Also Mostro updates the event 38383 about that order to change the status to canceled

I think a for a good UX the orders created by a user must have a button to cancel them.
