Improved auto-hiding of unused sockets for collapsed nodes.

Instead of generally hiding all unused sockets in collapsed mode, the sockets now have a new explicit flag SOCK_AUTO_HIDDEN, which is only toggled when the hide_toggle operator is called. This way the auto-hidden sockets stay as they are when nodes are duplicated etc. The new flag is necessary to distinguish between manually hidden sockets (via hide_sockets_toggle operator) and automatically hidden sockets and restore the node state when unhiding a node.
