Pointless access keys used in the menus

[Liam]

Access keys are used to quickly jump around different pages using keyboard shortcuts (Alt+Shift+<letter> on firefox). Since the navigation has changed a lot int he last few versions of Mahara, a lot of these access keys are now outdated and in some cases, obsolete.

Access keys that control buttons that open and close submenus arent needed any longer as they dont actually link to any other pages.

Only the ones like 'D' for Dashboard should stay as these link to other pages.

The access key changes will also need to be updated in the user manual:
c: content - No longer exists
p: portfolio - now called pages and collections
there are no longer separate admin and regular access keys as both menus are visible at all times
