Adds total cost field to send form, totalFeeCost variable to calculate using Bigint lib, sensible defaults in WalletTradeFormController, and template changes to match new logic
Modify function definition to pass minerFees as argument, hide MPCosts when viewing BTC in template. Remove calculateTotal from WalletSendAssetsController and into WalletTradeFormController. Add constants, make call to calculateTotal on selectedCoin change and on initialization within WalletTradeFormController.
Display total cost versus miner cost in the display template, modify logic to match, and modify user-facing statement.
