Merge pull request #24 from jmazzi/master

Add missing dependencies and Gemfile
Fixes to unit tests and updates to configuration to support CI builds using Travis CI

* Adds .travis.yml configuration file with entries for Ruby 1.8.7, 1.9.3 and 2.0.0
* Updates Gemfile to add dependency on "rake" required by Travis CI: we specifically add a dependency on version 0.9.2.2 to support use of "rake/rdoctask"
* Initializes Sequel DB object in test_helper.rb
* Enables the :after_initialize plugin for Sequel
* Restricts the required version of ActiveSupport to lower than 4.0.0 for Ruby 1.8.7 (CI builds only)
Rename test files and classes so they can run side-by-side with new tests
New tests to verify backwards data compatibility of legacy API

Note that marshalling changed significantly between Ruby 1.8.7 and Ruby 1.9.3 breaking compatibility, so we special-case Ruby 1.8.7 for the marshalling tests.
Merge of per-attribute IV and salt functionality from https://github.com/danpal/attr_encryptor

This change merges in the relevant commits from the attr_encryptor repository and introduces a new :mode option to switch between legacy behaviour (:single_iv_and_salt) and new behaviour (:per_attribute_iv_and_salt). For backwards compatibility, :single_iv_and_salt will remain the default.
