* Formatting fix

* Fix @sorpaas handle in author field

* Use EIP155 formatting for `CHAIN_ID`

* Formatting fix for "chain ID"

The document had places where we use lowercase "id" and uppercase "ID". This unify them to use uppercase "ID".

* Update eip-695.md

 ## Simple Summary

 Include `eth_chainId` method in `eth_`-namespaced JSON-RPC methods.
 
 ## Abstract

 The `eth_chainId` method should return a single STRING result
 for an integer value in hexadecimal format, describing the

 ## Rationale
+
 An ETH/ETC client can accidentally connect to an ETC/ETH RPC
 endpoint without knowing it unless it tries to sign a transaction or
 it fetch a transaction that is known to have signed with a chain
 ID. This has since caused trouble for application developers, such as
 MetaMask, to add multi-chain support.

 ## Reference
 
 Return value `QUANTITY` adheres to standard JSON RPC hex value encoding, as documented here: https://github.com/ethereum/wiki/wiki/JSON-RPC#hex-value-encoding.
