Link, Hide & reorder in Sprite list

[psineur]

I think it will be very useful to have Sprite List something like GIMP's layer list.
Linked sprites should be transformed together, when you transform one of them. No multiple selection needed - just apply delta of property from selected sprite to linked. Position & rotate should be enough.
Link flag should have free states: noLink, link, linkEndTop, linkEndBottom. Different chain icons should look good with this.
Two additional states: linkEndTop and linkEndBottom needed to prevent linking to groups into one, if they are near in sprites list.

Changing sprites order in sprites list needed to have ability to have many groups of linked sprites. Sprites that have linked flag will be linked only to sprites that are nearby and have linked flag too. Think about it like creating chains in sprite list. So it's possible to have only two additional references in CSSprite for above and below sprites.

Hide flag shouldn't make sprite invisible in CSD - only in editor.

These features will allow user to easily create menuItemSprites without supporting them directly.
