Summary: SCUMM: Bad memory access in filename substitution

Initial Comment:
This happens in the latest CVS snapshot, at least, and
has been happening for a while.

In some cases, the generateSubstResFileName_() is
called with 'filename' being an empty string. In this
case, it will be accessing filename[-1], which could be
bad.

I'm not sure exactly when this happens - I'm filing
this just so that Eugene won't forget about it - but
I'll give two examples of games where it happens for me:

* Monkey Island 1, data files monkey1.000 and
monkey1.001. To run this, I use a "monkey1" target.

* The FM-Towns Fate of Atlantis demo. To run this, I
use a "atlantisa" target.
