The same tabindex value on each subnav-list item

[Marcos Lobo]

On left panel, in the dashboard, each link (overview, instances, volumes, etc.) has the same value for tabindex attribute on <a> tag.

Tabindex attribute http://www.w3.org/html/wg/drafts/html/master/editing.html#the-tabindex-attribute indicate that an element is supposed to be focusable and specifies the tab order of an element.

If each link has the same tabindex value would not exist any kind of order. Each link should have a different value for tabindex.

    Added tabindex value to links in the sidebar.

    The tabindexes are reseted for each panel, beginning with 1. Because
    of the accordion nature of the interface only the links of one of them
    will be visible at any given time (the elementts with display:none
    will not be focusable).
