What changes did you make? (Give an overview)

Non-strict mode JS allows base-10 number literals to be preceded by zeros. This PR patches the rule to account for the case where more than one zero precedes an integer to determine its correct value.

Other cases, such as when an integer is preceded by a single zero, or when a non-integer value is preceded by one or more zeros are already handled correctly.

Is there anything you'd like reviewers to focus on?
