Nice control! (Some things)

[LJSDev]

• I must set [items retain] cause i had an EXC_BAD_ACCESS at init.
• I call 'fold' method an set 'on=NO' when i click on an item.
• i noticed that when i click a lot on the center button, the item's image stay visible sometimes.

the bad access with items happens if you have ARC turned off changing items to a property with retain fixes it.
