[patch] [ccla] ProgressBar: aria labels not correctly specified

[Becky Gibson]

When viewed with MS Inspect tool, the roles of the progress bar are not applied properly. The ARIA roles and properties need to be moved to the outer div element of the progress bar.

This isn't a huge problem because the label is specified and the screen reader is speaking the label but it would be better to have the role properly applied.

fairly simple change - needed to modify the template. Submitting for review in case I missed something.

Ah, I see I forgot to change this.label.id to this.labelNode.id in [22522], thanks for catching that. Note though that change is only for trunk, not 1.5.

Also, I don't see a need for a dojoAttachPoint=ariaProgress in the template, since you can just access this.domNode.

Other than that it looks OK.

One minor thing is that

var a,
    b,
    c;

is preferred over

var a;
var b;
var c;

because it saves a few bytes.
