Fix and cleanup Expanded Desktop Mode

no need to call state and mode several times from provider settings.
Cleaned up.

Also fix for the ugly lockscreen gap on expanded desktop
mode 1 and 3

And fix that mode changes reflects directly to the screen if
expanded state = 1

cheers

Frameworks: toggleQSShade (1/2)

we have a notfication shade toggle....but we cannot toggle
directly the QS drawer via SlimPIE, navbar or hw keys.

This commit does:
- bind qs shade toggle to slimpie, navbar or hw key
- logic detects if you are already in the notification drawer
  and switches then between qs and notification area. If not
  it closes the notification drawer or qs panel depending
  which of both is open
- icon changed to the same icons which are used in the notification
  drawer to have a visual consistence
- as well like the notificationshade toggle it is toggleable
  in expanded desktop mode or on fullscreen apps
- bindable as usual on normal and longpress actions
- for tablets it is of course just opening and closing
  due they have seperat notfication drawer and qs
