New Minor Version

With the changes described below we officially bump the minor version to 0.5.0 in this release of yulerc20

Changelog

• Added ERC20External.sol option for even more gas savings provided you do not need access to any of the methods marked external inside your ERC20 token implementation. (Many do not require these functions internally and you get additional gas savings this way)
