Uniswap integration
- Added a scripts/uniswap.ts file that does the integration (note: only works on Ropsten forks)
- Removed the check in Option.sol that required both accounts to have the same locked state (not sure if needed)
- Added methods in `scripts/contracts.ts' to display things in Dai and BTC correctly with mBTC as a supported option
- Adjusted the
scripts/testdata.ts
for realistic data
