update to select2's latest revision of master

apparently includes fix for ivaynberg/select2#1458

also update angular-translate 0.9.4, ditch the ~ for 0.0.x versions in
bower.json since they do not provide a stable api (e.g. angular-ui-utils
ditched ui-if in 0.0.3 (angular-ui/ui-utils#58)), add a .bowerrc to correctly
specify the component directory, and remove some cruft from the days of closed
beta.
