Fix problem with transations with scope, default and interpolation options
Validate localization key uniqueness only when localization_key is changed - it should increase performance a bit
simplify condition - if translated_value is present it can't be nil

Validate localization key uniqueness only when localization_key is changed
Merge pull request #24 from Bonias/refactoring

simplify condition - if translated_value is present it can't be nil
Translating not existing key twice should not set Lit::Localization#_is_changed to true

Set is_changed to true only if translated_value is changed.
Do the same for create_version.
Mark localizations as completed only is_changed is changed to true.
Move tests from pure_i18n_compatibility_extended_test.rb to lit_behaviour_test.rb

Merge pull request #21 from mlitwiniuk/exporter_refactor

Export method rewritten, possibility to define languages to export
typo fix
Change Cache#load_all_translations method
  - get rid of oninit argument because it is used nowhere
  - load translations to cache only when it looks like they are not loaded
Optimization:
  - save Localization record only when default_value is changed - ActiveRecord always save records(even when no changes are present) when one of columns is serialized
  - save nil values in redis cache
  - optimize deleting localizations - do not create localization only to immediately destroy it
  - fix saving default_value from options[:default] in lookup method - normalize keys first because options[:scope] should be applied too
