    Have Travis print out build logs in case of test failures
    
    To get the after_failure line work, I had to move the inline
    build script to a separate script (util/travis-script.sh)
    
    The second script (util/travis-after-failure.sh) will output
    LastTest.log for cmake based builds and all files named
    test*.log for an autotools based build.
    
    Note: this commit also comes with a delibarate test failure
    to illustrate the Travis behaviour. It will be removed in the
    next commit.
