Allow client to cancel order, And Remind for unpaid order
it would be nice to add option for clients to cancel their pending orders (the whole order and not some services) .
this maybe need to make change in the order plugin to inject a client
widget with their pending order, and add a button to cancel that order .
normally this can be done with a custom plugin , but the time we have is almost full .
a email reminder for client to pay their order will be also a nice feature .
