Before this, calling one of the loading functions with a nil argument always
made it return the default 0x0 surface. With this change, the passed-in default
value is now properly applied.

Previously, a Lua error was thrown when loading a file failed. Most callers are
not prepared for this and the result is less than optimal.
This commit makes the functions print the errors and return nil instead. For
callers that want to handle errors themselves, "_silent" variants of the
functions are introduced which just return errors to the caller.
