fix for the missing properties if we're consuming the /api/datasets backend of the newer dsapi server
upgrade angularjs to version 1.2.12
upgrade bootstrap to version 3.1.0
_theme.less is already included by bootstrap.less - no need to prepend it a second time
upgrade brunch to at least version 1.7 so that bootstrap 3.1.0 can be compiled by the bundled less plugin
