Support for ALLOW-FROM in XFrameOptionsFilter

A registry parameter was added to support ALLOW-FROM in XFrameOptionsFilter.

The registry setting is used to specify an absolute URL to your WFM instance when you want to display your WFM instance in an iFrame (inline frame) within your browser. This is often done when WFM is deployed as part of a solution with Infor Ming.le.

X_FRAME_OPTIONS_ALLOW_FROM_URI is for supported browsers OTHER than Chrome.

See "X_FRAME_OPTIONS_ALLOW_FROM_URI" in the Registry Parameter Reference Guide.
