Offer File Input

[BrandtH22]

Can the GUI be updated to reduce the number of button clicks needed to accept offers?
Ex. Instead of clicking on a button to popup a window for pasting an offer file can this be updated to allow users to paste the offer file in the text window already present?

It would also be beneficial to allow for multiple offer files to be accepted simultaneously/provide coin selection mechanisms to enable multiple offers to be accepted consecutively.
