Travis fixes

This seems to have the desired effect for me on my machine.

Note that 2 of the test comparisons are currently failing, one of them because it seems like a test file was mistakenly omitted from the commit.  One of the lines from the `Test_Error.dat` output is:

```
  nofit.dat.save not found.
```

Also: `displ.dat.save displ.dat are different.`, and the differences look pretty serious...

This will fail the Travis build (or should fail it, anyway), but the problems should be fixed in a different PR.  These are only github-specific changes.
