Ingo Schommer 26b52dd772 API CHANGE Upgraded jQuery UI from v1.6rc1 (r687) to v1.8rc3. This release prefixes all *.js and *.css files with 'jquery', so ui.core.js is now called jquery.ui.core.js.
API CHANGE Upgraded jQuery UI themes from v1.6rc1 to v1.8rc3. Removed 'flora' and 'default' themes, replaced with the 'base' and 'smoothness' themes found in the default distribution
