return XMLHttpRequest instance from Rails.ajax()

[glaszig]

useful for, e.g., implementing autocomplete features and canceling requests:

xhr = null
autocomplete = ->
  xhr?.abort()
  xhr = Rails.ajax()
  # ...

document.querySelector('.autocompletable-field').addEventListener 'keypress', ->
  setTimeout autocomplete, 250

While this change seems reasonable, I don't think Rails.ajax was intended for public use. It's a private helper for remote forms. WDYT @guilleiguaran?
