Fix typo - wrong bracket types for ENV in secret_token.rb
First step into FactoryGirl territory.  Call Numbers moved over in the absolutely trivial case.
Factoryized Floors
Libraries moved to factory.  DatabaseCleaner actually run after tests.
Subject Areas factoryized
MOAR TESTING, also some refactoring of tests.
Factoryized reservations and statuses
User spec factorized
Reorganized factories, corrected error in post spec (still fails, but fails for real fieldname)
Floor spec now accurately reflects acts_as_list
Typo fixed in spec
Name factored out into trait
Fixtures eliminated, factories ascendant
