- Loaded the time zone tables in mysql database
- Added Unicode/UTF-8 data support in usermergeDB and templates
- Replaced CLASS_SESSION_KEY with PLATFORM_SESSION_KEY in the session data as the latter indicates both user model and platform
- Corrected the session auth hash calculation method of both user models to take password (and platform, in case of User model) into account
- Enhanced template structure and functionality by using XHTML5 syntax, new HTML5 semantic elements, html5shiv.js, normalize.css, field labels, appropriate images/icons, etc. and moving internal CSS to base.css
- Made some minor changes in models (changed max_length of first_name and last_name fields) and database connection options (introduced SET_DEFAULT_STORAGE_ENGINE_TO_INNODB variable and changed SQL mode)
