Subject: [PATCH] fixing wrong item positions when moving more than one item
 down or up

- need to sort keys before moving, else we may end up with same result then before
- if moving items down respect the single static item 'search more'
- after moving set selected index to something human intuitive
- do not move items beyond boundary, just leave them where they are
