Reverted back to original Character model, using custom id slug as identifier for better synergy with Rails helpers.
Fixed migration type bug.
Attempted to manually set UTF-8 encoding.
Upgraded to mysql2 gem for better UTF-8 support.
Fixed issue with special characters comparing equal in some cases (for Character/Guild models in particular).  Fixes #22.
Added MySQL options to _create_characters and _create_guilds migration files to preset UTF8_bin to force binary comparisons instead of case insensitive comparisons.
Added recreate_db.rake file with app:reset task to force full refresh of database migrations instead of using schema.
