Portion of Bug 1664: Chart now shows problem weight * partial credit.
A new selection box 'Output Data' was created to seperate the output
mode (html, excel, csv) from the data being output.
The variable $base indicates the base (tries or scores) for the data
being output.
Modified all major routines (initialize, outputstudent, finish) for
each output method (html, excel, csv) to deal with this new structure.
Excel output of raw scores or tries on each problem part is now allowed!
Created &StudentTriesOnSequence and rewrote &StudentPerformanceOnSequence
to return the tries and scores.
