add $browser.defer and $defer service and fix async xhr cache issue

- Closes #152 ($resource().query() sometimes calls callback before
  returning, and it shouldn't)
- add $browser.defer method
- add $defer service
- integrate $browser.defer with outstandingRequests counter in $browser
- fix all old tests that relied on buggy behavior
