Reworked resizing of items on board. Still have troubles with resizing at BottomRight resizer.

Selected items can be moved by any frame of any item.

Audio items cannot be resized in vertical dimension because there are no useful content.

Audio and Video items has minimal dimensions.

SANKORE-774 - toolbar disabled for all items instead media and text items. It allows to calculate items bounding rect correctly.

- locked items is not editable now.
- toolbar for text item hides when item is locked

Fixed behavior of toolbar:
toolbar of media items hides after 5s of idle.

Locked items cannot be moved horizontally by its frame.

Text items can be resized correctly now.
