Comment 2 for bug 1399148

The bug is caused by the Ubuntu using python-xstatic-bootstrap-scss_3.1.1.1-1, while CentOS uses XStatic-Bootstrap-SCSS-3.2.0.0. These 2 versions differ at least by the value of $modal-inline-padding which is 20px for Ubuntu (older package) instead of 15px for CentOS (newer package) - which is in turn causing 2-column modal forms to break. Bumping to next version because changing the version of Bootstrap package can have a major impact on UI appearance and we have to verify that it works and looks fine.
