Make coveralls work

[cdeil]

@astrofrog As you can see here python setup.py test --coverage now works for photutils, but coverall tries to submit files for an Astropy coverage report instead of for photutils.

What configuration needs to be changed to make this work?

Coveralls started to comment on photutils pull requests yesterday ... I don't know if we want this (I don't care either way).

But it still doesn't work ... latest example here shows that it's still trying to submit coverage reports for Astropy, not photutils files:
https://travis-ci.org/astropy/photutils/jobs/25633099#L617

$ if [[ $SETUP_CMD == 'test --coverage' ]]; then coveralls; fi
Submitting coverage to coveralls.io...

I disabled the commenting. I'm going to take a look at this.

@cdeil - I think this may have been fixed in the dev version of astropy. Can you make it so the coverage testing is done with the dev version of astropy?

[cdeil]

@astrofrog Yes, submission to coveralls does work with the dev version of Astropy, thanks for the tip!

@astrofrog I think this is ready ... can you have a look?
