[Xsltforms-support] [PATCH] Prefer XHR over ActiveX so IE7 works even wih higer security restrictions (when ActiveX disabled)

[Kostis A. <ank...@gm...>]

Hi,

Acording to [1] from IE-7 and later, they support XHR object and it is
prefferable to use it instead of the ActiveX equivalent.
My problem was that we had browsers configured within stricter
security zones, and they had ActiveX disabled.
Also i followed the advise on [1] about the ActiveX string-label to
use when getting the XHR,
and modified code to fetch the latest XHR version.
