Location#search should return Location

[rparree]

Many of the Location methods return this, like for example search. This allows a syntax such as:

$location.search("code","ABC").path("/people/edit")

Location most likely should look like

trait Location extends js.Object {

  def absUrl(): String = js.native
  def url(url: String = null, replace: String = null): Location = js.native
  def protocol(): String = js.native
  def host(): String = js.native
  def port(): Int = js.native
  def path(): String = js.native
  def path(path: String): Location = js.native
  def search(search: js.Any, paramValue: js.Any = null) : Location = js.native
  def hash(hash: String = null): String = js.native
  def replace(): Location = js.native
}
