Support for WebAssembly (WASM) smart contracts

[treeder]

WebAssembly has become a browser standard and is gaining steam as the new way to develop for the web. https://webassembly.org/ While it was intended for browsers, it's properties are actually very nice for blockchain development too.

• Small binary format
• Near native speed (better then EVM)
• Multi-language support

Having this on GoChain would enable a whole new realm of developers that don't know Solidity and would not have to learn solidity to write smart contracts.
