CR: Add FileObject static utility methods

Synopsis: Add utility functions that creates an
IHXFileObject from an 
URL or an IHXBuffer and sets the request. These methods were
created 
for the Flash Guest Player, which uses FileObjects to
provide the 
data to the Flash plugin.

Overview: Added two static methods:
HX_RESULT 
CHXSingleBufferFileObject::CreateFileObjectWithRequest(IHXBu
ffer* 
pBuffer, const char* pszURL, REF(IHXFileObject*)
rpFileObject, 
IUnknown* pContext)
	- Create an IHXFileObject from pBuffer and set the request
on it with pszURL.
HX_RESULT
CHXSingleBufferFileObject::CreateLocalFileObject(const 
CHXString& pszURL, REF(IHXFileObject*) rpFileObject,
IUnknown* pContext)
	- Read the local file specified by pszURL into an
IHXBuffer, call 
CreateFileObjectWithRequest to get the IHXFileObject and set
the request.
