Title: Fix a hardcoded callback function

Although you are supposed to be allowed to pass custom callbacks, the default callback is hardwired when updating the defaults, therefore all other callbacks will fail as the persistent variables for screen
identifier etc are never set up. This fevals the callback function as long as it is a valid file.

See Psychtoolbox-3/Psychtoolbox-3#85 for more details.
