More changes to user page.

#1517 

More changes to the user page.

 * "Edit" local menu task tab changed to "Edit Account"
 * "Add a new site" link added
 * User edit page title changed to mimic user view page (firstname lastname displayed if set, if not defaults to username)

@rbran100 can you take a quick look and make sure I'm calling the correct access check to allow the "Add a new site" link to appear?
