Fix for Question Format issue #603

[briri]

This patch updates the seeds.rb file that new installations use to seed their database tables. The file was missing the question_formats.formattype field and the token_permissions_type table was missing entries for 'templates' and 'statistics'

Well spotted Brian, we did not seed these format types. The reason of the oddity is due to the front using the enum types for displaying the questions types whereas the admin is using string comparison. We should update everything to use enum types when bootstraping the admin part.
