Bug 5589
In exam mode, optionresponse and matchresponse problems in a single part are divided into sub-questions, each one with its own scantron bubble line(s).

In exam mode, essayresponse, formularesponse and stringresponse can have multiple bubble lines associated with a single part, and bubbles in more than one of these lines, if the weight assigned to the part exceeds 10.

These two cases are addressed.  The first, by passing scantron data lines to the validator for each of the sub-questions in turn, and the second by performing the occurrence_count check on each line in turn.  Some bookkeeping code has been added to keep track of data for each subquestion.

-  %subdivided_bubble_lines hash provides a place to store bubble lines per subquestion for optionresponse and matchresponse.
- %responsetype_per_response provides a place to store the responsetype for each response.

- In the case of essayresponse problems, items are not included in $analysis{'parts'} from lonnet::ssi, so possible part IDs need to be retrieved from the  $resource object.

- When preserving information about missingbubbles, use questionnum (which includes subquestion) instead of question.

- Validation for the different scantron formats - letter/number or positional moved to two subroutines - &scantron_validator_lettnum(), and &scantron_validator_positional().

- &prompt_for_corrections() can return an array containing numbers of lines with missingbubble or doublebubble.

- This array is passed to &verify_bubbles_checked() which provides a javascript function to alert the user if any lines are without a choice of bubble or 'No bubble' for the current validation screen, for missingbubble or doublebubble cases only.

- Data tabling the validation tables for missing or double bubbles.

- Fix some typos and expand the documentation for bubbling multiple lines for essayresponse, formularesponse or string response (where more than 1 line may contain a bubble).
