All this method of the Rails' request class does is to check whether
the request is "ajaxian" ('xhr' is a common acronym for
XMLHttpRequest). It's handy for rendering responses.
Of course, the generic paste request class must not have it, as the
method relies on ptototype's sending the corresponding header. However,
Pylons uses prototype, therefore such a feature could be used here.
