TravisCI fixes
TravisCI fixes

Travis started failing with this error:

      File "/home/travis/miniconda/lib/python2.7/os.py", line 157, in makedirs
        mkdir(name, mode)
    OSError: [Errno 13] Permission denied: '/home/travis/.cache/pip/wheels/b7'

I fixed this by chowning all of ~/.cache to travis:travis
Also changed the verbosity of the install_caffe script
