Fix outline and tab order of items in the toolbar

[alansemenov]

1. HomeButton should not be clickable in Content Studio and Applications (keep it in the Users app since there we still have wizard tabs).

2. When the app's main page opens, the Launcher button must be focused and have visible outline:
   

3. Tabbing out of the Launcher button must follow logical order of elements. For example, in the Content Studio focus should go from the launcher button to search icon, then New action button etc. It seems to work in Chrome, but in Firefox outline is not visible. It seems that the only element that is visibly outlined in Firefox is the Publish button in the grid toolbar.

4. NonMobileDetailsPanelToggleButton never gets a focus. It must be focused after the Publish button or - if it's disabled - right after the last action button in the toolbar.

5. In the Content Wizard when I Shift-tab from display name, then to the content icon, and the Publish button gets focus. This is wrong - there are toggle buttons to the right of the Publish button which must get focus in correct order (if they are visible and enabled, of course).
