Added two macros, ICOM_VFIELD and ICOM_VTBL, so that when implementing

a COM interface one never has to name the lpVtbl field explicitly.

* Comments:
* - In C++ IDirect3D does double duty as both the virtual/jump table and as the interface
* definition. The reason for this is to avoid having to duplicate the mehod definitions: once
* to have the function pointers in the jump table and once to have the methods in the interface
* class. Here one macro can generate both. This means though that the first pointer, t.lpvtbl
* class. Here one macro can generate both. This means though that the first pointer, t.lpVtbl
* defined in IUnknown, must be interpreted as the jump table pointer if we interpret the
* structure as the the interface class, and as the function pointer to the QueryInterface
* method, t.fnQueryInterface, if we interpret the structure as the jump table. Fortunately this
