Removed old IE XDomainRequest client and xhr and xdr interceptors

Old IE is no longer supported or tested. Removing code dedicated to old
IE that is not interesting to any other environment.

The client and interceptors will still work, if needed, they can be copied
directly into a project.

-#### Cross Domain Request for IE Interceptor
-
-`rest/interceptor/ie/xdomain` ([src](../interceptor/ie/xdomain.js))
-
-Utilizes IE's XDomainRequest support via the [XDomainRequest client](clients.md#module-rest/client/xdr) for making cross origin requests if needed, available and a CORS enabled XMLHttpRequest is not available.  XDR request have a number of limitations, see the [XDR client](clients.md#module-rest/client/xdr) for limitation details.  Will not interfere if installed in other environments.
-
-This interceptor should be installed as close to the root of the interceptor chain as possible.  When a XDomainRequest client is needed, the normal parent client will not be invoked.
