Fix for visual sidebar glitch on builds page

There are two divs on this page using the same id of "content"

<div id="content-wrapper">
    <div id="content">
        <!--outlet-->
        <div id="sidebar"></div>
        <div id="content"></div>
        <!--/outlet-->
    </div>
</div>

This causes a CSS glitch on the sidebar menu. Referencing the other pages it seems this external "content" div is not needed and removing fixes the CSS glitch.
