/*********************************************************************
* Function: DWORD HTTPIncFile(TCP_SOCKET skt,
* DWORD callbackPos, ROM BYTE* file)
*
* PreCondition: curHTTP is loaded
*
* Input: None
*
* Output: Updates curHTTP.callbackPos
*
* Side Effects: None
*
* Overview: Writes an MPFS file to the socket and returns
*
* Note: Provides rudimentary include support for dynamic
* files which allows them to use header, footer,
* and/or menu inclusion files rather than
* duplicating code across all files.
