Fix syntax and escaping of window.location properties.

Fixes to window.location per MDN and empirical testing w/ Chrome:
* window.location.{pathname,search,hash} are in escaped form.
* window.location.host correct when no port number is present.
* window.location.pathname is never empty, but at least '/'.
* window.location.{search,hash} include the ? or #.
* Fixed cases where 'nosuchhost.invalid' placeholder values occur
  even though there is a proper value, which happens to be the empty
  string.

Supporting changes:
* Move testLocation from test-domado-dom-guest to test-domado-global and
  run it on several different URLs.
* Refactor test-domado-global to introduce registerGlobalTest which can
  handle more cases than registerGuestTest.

for a specific url (that we're not being consistent but incorrect)
I had trouble reading the parenthesized comment, perhaps recast? You mean:
  (that we're not being (consistent but incorrect))
but it was easy for me to misread:
  (that we're (not being consistent) but [are] (incorrect))
