add mandatory "security considerations" to EIP-1 and template EIP-x

EIPS/eip-1.md

@@ -84,6 +84,7 @@ Each EIP should have the following parts:
 - Backwards Compatibility - All EIPs that introduce backwards incompatibilities must include a section describing these incompatibilities and their severity. The EIP must explain how the author proposes to deal with these incompatibilities. EIP submissions without a sufficient backwards compatibility treatise may be rejected outright.
 - Test Cases - Test cases for an implementation are mandatory for EIPs that are affecting consensus changes. Other EIPs can choose to include links to test cases if applicable.
 - Implementations - The implementations must be completed before any EIP is given status “Final”, but it need not be completed before the EIP is merged as draft. While there is merit to the approach of reaching consensus on the specification and rationale before writing code, the principle of “rough consensus and running code” is still useful when it comes to resolving many discussions of API details.
+- Security Considerations - All EIPs must contain a section that discusses the security implications/considerations relevant to the proposed change. Include information that might be important for security discussions, surfaces risks and can be used throughout the life cycle of the proposal. E.g. include security relevant design decisions, concerns, important discussions, implementation specific guidance and pitfalls, an outline of threats and risks and how they are being addressed. EIP submissions missing the "Security Considerations" section will be rejected, submissions without a sufficient security discussion may be rejected.
 - Copyright Waiver - All EIPs must be in the public domain. See the bottom of this EIP for an example copyright waiver.
