* New EIP describing standardization of JS Ethereum Provider <=> Client communication.
This is spun off of EIP-1193, which I believe to be too large. This extracts out *only* the critical pieces of the RPC specification, leaving out unrelated sections of 1193.
* Adds EIP Number from PR number.
* Rename eip-TBD.md to eip-2696.md
* Fixes spelling error.
