Subject: [PATCH] Add support for endLine and endColumn

Add support for creating a full range from an ESLint message if it
specifies an `endLine` and `endColumn`. Also adds a `validatePoint` helper
function to check that these coordinates given from ESLint are valid since
we no longer have the checking built into `helpers.rangeFromLineNumber`.
