Update Wizards

t3oodle ships currently one upgrade wizard, to make it easier to apply structural changes.

Migrate old “One option only” setting

In t3oodle 0.6 the poll setting “oneOptionOnly” has been changed to “maxVotesPerParticipant”. This update wizard checks “tx_t3oodle_domain_model_poll” table for old setting set and migrates it to new option.
