Branches: MAIN
CVS tags: HEAD

Simplify user interface.  After chatting with Felicia the following
changes have been made to the 'Output Data' selection:

'Scores' has been renamed 'Scores Per Problem'
'Scores Sum and Maximum' has been renamed 'Scores'
'Scores Sum' has been removed.
'Scores Summary Table Only' has been removed.
'Tries' remains the same
'Parts Correct and Maximums' has been renamed 'Parts Correct'
'Parts Correct' has been removed.
'Parts Summary Table Only' has been removed.

Removed means access to that option has been disabled.  Can be re-enabled
without trouble in response to the inevitable outcry.
