Issue #2368809 by mrded, thehong: Fixed Results page renders very slow.
Remove deprecated _quiz_format_mod(). Much better in D7.
Removed dead code theme_multichoice_response. Moved to getReportFormResponse().
Removed old < D7 code to do crazy things with input formats.
Coding standards: rename multichoice_row to multichoice-row.
Fixed textarea title not being hidden like in 4.x.
Improved quiz auto-title.
