Adding in Persona Bar Hover Menus + Fix for Removing Edit bar on Cancel-Edit-Button-Click

[CBPSC]

This update provides hover menus for the persona bar

Right now we have 3 icons (Content, Manage, Settings), but hopefully the Persona Bar would be extensible meaning other developers could add items into it.

In that case I'd need to account for the new items developers added for some of the menu show/hide actions. To do that I'd make an array of Persona Bar items and loop through them so that when a menu item is hovered over... then the user goes directly above or below with the mouse to another menu icon item... the (newly added in item) would not show it's menu.

This would be added to the closeAllMenus() function

Overall it looks good, but there are a couple things that need address:

• see review comments on code
• please merge with master since this branch is conflicting
