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 git-svn-id: svn://svn.silverstripe.com/silverstripe/open/modules/sapphire/branches/2.4@100842 467b73ca-7a2a-4603-9d3b-597d59a354a9
