WINTERMUTE: Fix assertion in Hamlet game

Assertion was caused by providing "saves/" prefixed string to
WindowsFilesystemNode::getChild() function, that asserts on '/'
characters.

Wintermute game code:
if(!(Game.FileExists((Game.SaveDirectory + "\gamelet.save")))) {
Directory.Create(Game.SaveDirectory);
}
...

Assertion stack:
from C:\WINDOWS\System32\KernelBase.dll
from C:\WINDOWS\System32\msvcrt.dll
