Wrong spark lines shown if dev focus branch not first

[Tim Penhey]

https://code.edge.launchpad.net/~thumper shows the launchpad spark line for the lp:mad branch.

This is due to the following code getting the the json_url from the first branch, rather than checking which branch it should be getting it from. Which brings up another bug, only one spark line is shown even if I have subscribed to many branches that are development focus branches.

function renderSpark() {
    spark_div = 'dev_focus_spark';

    if(Y.get('#' + spark_div) !== null) {
        json_url = branch_sparks[0][1];
        var container = spark_div;
        var uri = json_url;
        var xhr_config = {
            on: {
                success: doUpdate,
            },
            arguments: {
                'container': container
            }
        };

      Y.io(uri, xhr_config);
    }
}

Martin, I'm assigning it to you as we need to decide how many to show, and also how to fire off a whole pile of non-blocking update requests (if sending off multiple).

We should show sparklines for all branches on a person's page. On product listings, we show only the dev focus because there's not much variation between branches. However, on person listings, we can expect a great deal of variation (and often no development focus).

lp:~thumper/launchpad/sparkline-listings makes it so the javascript array branch_sparks contains the urls to hit.

See https://code.launchpad.dev/~name12

The branch_spacks array has two values, the first is the id of the div to replace, and the second is the url to get the values.

You probably want to consider changing the styles on the dev_focus_spark div, or perhaps killing it all together.

Didn't make PQM, due to a facepalming oversight by myself. :/

Retargeting to 3.0, which is the new name for 2.2.9. Haven't renamed the milestone as the 3.0 milestone is in a different series.
