New script to update name of content objects

*Title: New script to update name of content objects

*Documentation:
The new update/common/scripts/updatecontentobjectname.php script is based on the updatesearchindex.php script.
When running it, it updates the name (from the content class' "object name pattern") of each content object and stores them.

*Testing:
1. Look at a directory listing objects of a certain type (content class) using the node.name attribute to list objects.
2. Edit object name pattern of the content class
3. Look at the directory again - the names have not changed.
4. Run the updatecontentobjectname.php script
5. Verify that the name has changed.
