Config throws a "couldn't read resource" exception when the file is in the classpath but it's #included file is not.

```
Read a file with Config that contains an #include statement. If the
included file is missing, the exception thrown by Config is misleading,
stating that the file that could not be read is the main file, not the
included file.
