2.0.0.0-dev33
* Improved Themes functionality to meet the following requirements:
  * Magento instance doesn’t crash in case there’re no themes at all
  * Features like selection of themes in system configuration, custom theme selection in Custom Design, CMS pages, Products and Categories can work without themes. They use base view files only.
  * Virtual themes work in the same way as the non-virtual (which are present in file system) though they additionally have inheritance property. Changes were made in theme switcher, in fallback mechanism, in widgets etc.
  * Non-virtual themes are being added to DB during installation
  * Application framework uses theme id as identifier instead of theme code
* Refactored a variety of report grids in backend (admin) to make them configurable through layout, rather than hard-coded.
* Removed obsolete modules:
  * `Mage_XmlConnect`
  * `Mage_Dataflow`
* Significantly changed Logging subsystem:
  * `Mage_Core_Model_Logger` class is responsible for logging
  * Changes are made to comply with DI paradigm
  * Custom logger in `Mage_Backend_Menu` subsystem is removed due to usage of regular one
* Changes made in autoload process
  * Fixed autoload to prevent `class_exists()` from causing fatal error
  * The `Magento_Autoload` library was divided into 2 classes: `Magento_Autoload_IncludePath` is responsible for loading from include path, `Magento_Autoload_ClassMap` from a class map. Stacked "class map" loader on top of "include path" loader in application bootstrap.
* Implemented new jQuery form widget. Its responsibility is to prepare form for submission (change form attributes if needed)
  * Replaced usage of different instances of `varienForm` with a new form widget (`productForm`, `categoryForm`, instances of type "onclick declaration", "as child component", "instantiation only")
  * Replaced prototype validation with jQuery analog
  * Additionally implemented form widget in different modules (CMS, Customer, Backend, Sitemap, DesignEditor, Tags, SystemEmail, Newsletters, ImportExport, Connect, Authorize.net)
* Minor improvements
  * Fixed css styles for validation messages in different parts of the system
  * Removed usage of `jquery-ui-1.8.21.custom.css`
  * Updated versions of jQuery and jQuery-UI on backend
  * Updated Magento trademark and copyright labels at the bottom of pages: changed legal entity name to X.Commerce, Inc, made translation engine pick them up
