0.8.0.beta1

Notable changes

• You can now set I18n.cache_key_digest to determine how cache keys are calculated. If you were seeing issues where the same value stored in a cache produced a different key, then this fix will interest you. For more information, see #285.
• You can now override translate_format in I18n::Backend classes to customize how localize will perform. See #347 (comment) for more details.
• You can now interpolate the value of a key inside another key. See #300 for more information.
• The exists? method was added to the fallback backend, to match other backend implementations - #326
• Added N_ to GetText::Helpers - #121
• Added a :default option for I18n.localize - #251

Bug fixes
