- Bug 6476
  - Store rawrndseed for parts with all responsetypes.
  - Eliminate storage of rndseed, since rawrndseed is the item needed to
    reconstruct the randomization for a problem in Authoring Space.
  - If questiontype is randomizetry rawrndseed and rndseed are the same,
    so use rawrndseed from the submission history, where it exists.
  - Support use of randomizetry for script blocks outside a part block in
    problems with a single <part></part> tag.
  - Support use of randomizetry for script blocks inside part blocks.
Note: randomizetry does not apply to randomization in script blocks
outside part blocks for problems with multiple parts, because the
number of tries is not uniquely defined.
