Update kineticjs.d.ts

- `Line` has property `dashArray` not dash : http://kineticjs.com/docs/Kinetic.Line.html  
- there is no `remove` function on `Container` : http://kineticjs.com/docs/Kinetic.Container.html that takes a child
- there is however a `remove` function on `Node` that removes an item from its parent. http://kineticjs.com/docs/Kinetic.Node.html This function exists in Container as well http://kineticjs.com/docs/Kinetic.Container.html (since container inherits from Node)
