Comment:

 Patch updates the stacking contexts for the main cover image block
 groups/members header elements.

 This patch corrects the issue of prior elements having a lower context
 (non position relative)

 Tested across twenty* themes & IE9

 The update re-sets the inner contexts to 1 & 2 respectively for the
 background image and BP item-avatar and item-actions container.

 The parent container is set to '0'

 This corrects a greater issue spotted in twentytwelve where the parent
 cover-image container having a higher context than the main menu
 completely overlays the dropdown menu, obscuring the majority of the menu
 items.

 In reality setting the cover image parent wrapper to '0' is sufficient to
 correct the initial problem with high z-index, we'll set parent = '0' and
 within that context set the elements to '1' & '2' to be safe, stating the
 obvious in a sense.
