Actions mentioned with button Actions on Contact Summary are only in Contact_BAO_Contact::contextMenu, should be option list

we should add new hook that would allow users to customize contextmenu actions on Contact Summary

• civicrm_summaryActions( &$actions, $contactID )
• add example for it in civitest.module.sample
• update the hook documentation on wiki

– Original post --------------
In the Contact Summary there is a button 'Actions' which lists all possible actions for a Contact. At the moment this is hard c oded in Contact_BAO_Contact::contextMenu. This should be moved to an option list so the customer can decide which actions are available here. Now it can be they make activity types disabled but they are still listed with the actions button?
