jquery-ui was regenerated to up to date version. Border radius and IPA custom colors were added to theme so we don't have to override them in ipa.css. https://fedorahosted.org/freeipa/ticket/2817
Facet tabs are now colored according to their group. https://fedorahosted.org/freeipa/ticket/1976
The images have been renamed to be more consistent and moved into the "images" directory to mimic the original jQuery UI structure. Ticket #1613
