Avoid shadowing existing declarations (improvements to EIP20) (#1437)
* Avoid shadowing existing declarations
About optional methods, Solidity compiler currently throws this warning: "This declaration shadows an existing declaration.". I suggest to remove names from return parameters of the optional methods to avoid shadowing existing declarations.
* More improvements
- Fixed warning about visibility
- Links to examples are now permanent links
- Added note about Solidity version used in the specifications
