Routine Description:
Retreive a profile value as a unicode string.
Arguments:
ValueName - supplies the name of the value to be retreived.
DefaultValue - supplies the default value, which is used if
the given value cannot be retreived for any reason.
Return Value:
Pointer to the profile value. The caller can free this
buffer with MyFree when done with it. Note that this
routine always returns a valid pointer.
