PolkadotJS Browser Test

The extension is optimized for usability and hides complexity. Compared to the Pioneer UI where three algorithms can be selected for key creation the extension uses sr25519 for creation abd is able to import other types as well (polkadot-js/extension#339).

The minimal password length is 6 characters while Pioneer has no restrictions.

Cross-chain keys have been tested with https://testnet.joystream.org and https://polkadot.js.org.
