Make it possible to initiate transactions on the Ethereum blockchain directly from within High Fidelity. This would allow some useful things:
1. Two avatars can pay each other for goods or services, using either the base Ethereum currency or any ERC20 token, such as one of the emerging 'stablecoin' standards such as USDT.
2. Add the general ability to read/write to Ethereum to enable identity and other apps such as uPort.
