White space / end-newline cleanup

Annoying little clean ups for the 2.2.1 release

Hi @BryanGuillaume,

Here are the tweaks I mentioned in comments on #178... all fixed... merge this into your branch and then the 2.2.1 PR should be ready to go.

For the record, all I did was run these two commands

for f in .travis.yml *.m */*.m ; do gsed -i 's/[ \t]*$//' $f; done
for f in .travis.yml *.m */*.m ; do gsed -i '$a\' $f; done

@nicholst, thanks for this. I really appreciate this kind of clean up!
