Updating the swap and more.

We've updated the swap tab for you. We've added a slippage setting and its subsequent editing, adjusted colors, layout, and much more. We've fixed the transition from the token information tab to the swap tab so everything now works correctly. We've also updated the balance display and the tokens available for swap. We've also updated the search function, which is now available not only by contract address but also by text.
