The old code has to be removed and remaining bugs fixed.

Show desktop: "Add folder" make sankore freezes after virtual keyboard was opened

UBToolWidget API has been deactivated, there is certainly a lot of bugs, code is ugly.
Remember to fix commented sections (forgotten which ones).

Implemented Sankore-729 - previews images for web search results supports images, audios, videos and flash content.
Images previews is adjusted now.
Mime type detection mechanism is more common now.

Fixed a bug - grouped items cannot be dragged by itself now.

Items can be moved by RubberBand.

It's icon is temporary.

Behavior implemented:
1. Can interact with all items without showing items frames (but ToolBar shows).
2. Cannot move items, but can drag images.
3. Selected items appears deselected when Play tool chosen.
4. Play tool don't requires selecting of item before interacts.
5. Cursor looks like tool icon in text and image widgets (should be the same in any others widgets, but now in w3c is not).
