Added an option to display the selected historical graph embedded within the floating window
Traders can choose to have the historical graph alongside the XCountry spread table, this way the data is all in one window to avoid additional windows.

Enhancement #2
Support sending of trades directly to the Sprd/Bfly window
On the bottom right of the historical graphs, the “To Sprd/Bfly” button will send the strategy to the Sprd/Bfly. This way traders can add strategies to their Sprd/Bfly with the click of a button.
