Backward compatibility fix for SOCK_DYNAMICS flag on group sockets.

Browse Source 
This is currently only needed for displaying the up/down buttons of group sockets. All regular group sockets should have this flag to indicate they are added by the user. More complex "group-type" trees may use non-dynamic sockets in the future for sockets that are not supposed to be manipulated.
