patch

For some reason I don't understand yet this patch helps. It still fails later
but differently:

---
003e:trace:scrrun:filesys_OpenTextFile (0x7d0f1e74)->(L"\acad.rx" 8 -1 0
0x76e350)
003e:trace:ole:DispCallFunc retval: 0x76e360->{VT_ERROR}
003e:trace:ole:ITypeInfo_fnInvoke [retval] value:
0x1436608->{VT_DISPATCH|VT_BYREF,0x76e350}
003e:warn:ole:ITypeInfo_fnInvoke invoked function failed with error 0x800a0046
---

Reason for that is 'inACADSupportDir' argument in a script being empty string,
making path invalid. I'll try to figure out why hreftype lookup is fixed with
such idl changes first.
