Bootstrap gives us a 12 column grid, but we're only using 11 of the columns, so we're left with extra whitespace on the right side of the page. We should add 1 to one of the divs, probably the diff div since its set to the smallest amount currently:
col-sm-3 page-div -> col-sm-3 page-div
col-sm-1 diff-div -> col-sm-2 diff-div
col-sm-2 report-div -> col-sm-2 report-div
col-sm-3 wikiproject-div -> col-sm-3 wikiproject-div
col-sm-2 status-div -> col-sm-2 status-div
