fixed Travis-CI failed. https://travis-ci.org/borisyankov/DefinitelyTyped/builds/18779631
addMethod params arguments vs array syntax

jQUery Validation does not send arguments but an array of the argument already built. By using the ... syntax of TypeScript, we get an array with one item that has the array sent by jQuery validation. I think the definition should use an array instead of arguments syntax.
Changed the any[] to be any

jQuery: JSDoc completeness within reach

jQuery: tests now cast to svgjs.LinkedHTMLElement

This could be made implicit by extending the JQuery interface with:
get(index: number): svgjs.LinkedHTMLElement;

Looking at the library it didn't seem sensible to create a dependency on
jQuery even though the tests have one.
