Cancel order(s) option in orderbook on Exchange

**Is your feature request related to a problem? Please describe.**
Scrolling through order books and cancel a order needs a switch to MY OPEN ORDERS.

**Describe the solution you'd like**
Add the cancel order icon also to the BUY/SELL ORDERS afterwards.

**Describe alternatives you've considered**
Only make a right-click context menu to cancel the order in BUY/SELL ORDERS.

Start by locating the orderbook view and the existing MY OPEN ORDERS cancel-order control. Compare how the BUY/SELL ORDERS entries are rendered and how cancellation is triggered; done means users can cancel those orders through the added icon or an agreed right-click action.
