Settle in Anything: Perpetuals

When closing a perp position, option to settle in any token (that is supported by swap). The swap can happen behind the scenes. The default should be the token used to purchase the perpetual and not the underlying contract, so if i use jlp to long sol, i should get back jlp. Havent shorted but this would be particularly important in short positions.


…also, the liquidation price and pnl should be displayed in both the collateral used and usd. This is the most honest assessment of return.
