left align pre tag text

[smcoll]

Profller output, in a pre tag, is centered, due to an inherited rule for #query-div in summary.css:

#query-div {
    margin: auto;
    width: 960px;
    text-align: center;
}

@smcoll I am rerunning the CI build before merging. I believe TravisCI is in a transition to Ubuntu Trusty and some builds failed because of it.

@smcoll Thanks for the CSS enhancement!
