userportal, webadmin: upgrade gwtbootstrap3 to 0.8.1

Upgrade gwtbootstrap3 from 0.6 to 0.8.1. This upgrade was waiting
for GWT 2.6, on which it is dependent.

For the features we are currently using, this new version appears
to be drop-in compatible.

gwtbootstrap3 0.8.1 adds previously unimplemented features of
bootstrap, such as a Tooltip widget.
