Remove calendar hack
Update pebblebed
Upgrade to ActiveRecord 4.0 and sinatra-activerecord 1.4, which can replace the database tasks in bengler_test_helper. This also means using schema.rb instead of development_structure.sql.
Fix Post#visible_to? and Post#with_restrictions to check that identity is god in the correct realm.
Use pebbles-river instead of the implementation in Pebblebed.
