Travis CI configuration, the final one?

The problem is that Travis needs the browser to be specified as well in
the Gruntfile, in addition to the “browser” section of the
karma.travis.conf.js file. If I added there as well, then the test is
repeated two times locally in my computer. So I am checking if I can
keep the browser specification in the Gruntfile and remove the browser
from the configuration file for travis (again, karma.travis.conf.js)
