Data Processing post-bootstrap 3 UI fixes

Some of the data processing forms were showing extra fields
that should have been hidden.  That was fixed by using
form-group rather than control-group.  Also, the cancel button
was missing its outline on some of the forms because it was
missing the btn-default class.  Other buttons used to choose
libraries and add configs were also missing btn-default.
* Details pages had a large gap, fixed row-fluid --> col-sm-12
* row-fluid --> row in other places per migration guide
* icon-plus/minus --> glyphicon-plus/minus
* select inputs have now have form-control class
* unnecessary margins deleted for "Remove" buttons
* list-style added for node processes <ul>
