V10.10: occ now needs to have executable file permissions

A heads up to those following manual upgrade procedures:

The upgrade manual has been updated to reflect a new command structure for occ.

Old: sudo -u www-data php occ
New: sudo -u www-data occ

This is nice because the occ file runs /usr/bin/env php as a script…however, your occ file needs to have executable file permissions in order to run as a script. The manual currently shows all files are to be set to 640 permissions, but the occ file will need at least 670 temporarily in order to run the new command structure properly.

I prefer to leave it at the package default of 755. There is no reason to grant write privileges to the group.
