Migrate: 'Event.disable_auditing' is undefined method?
Devise 2.0 needs new schema style

Followed docs on https://github.com/plataformatec/devise/wiki/How-To:-Upgrade-to-Devise-2.0-migration-schema-style
(plus modified to fix subsequent migrate errors)
Migrate: conf day_start/end, was not fixed correctly?
Migrate: proper day_start/day_end conversion
Merge branch 'bug_migrate_dayStartEnd' of https://github.com/tias/frab into tias-bug_migrate_dayStartEnd
adds migration to make remove products migration work later on

Originally the product tables were included in schema.rb. They were
later removed using a migration. However no migration to create them
existed making `rake db:create; rake db:migrate` fail.
This doesn't affect the document way to create a frab db, as
`rake db:setup` continued to work.
