Dear LimeSurvey developers
First, thanks for this amazing project and congratulations for your work.

I have deployed Limesurvey to setup a survey to free/open source software developers and contributors, and some of them complained that the Firefox plugin LibreJS blocks part of the JavaScript, as if it was non free.

I have researched a bit, and the problem seems to be that the JS code is not tagged in a way that this plugin recognizes the license of each .js file (or code embedded in other files).

For example, LibreJS complains about this files:

in attribute: onchange:javascript:$('[name=move]').val('changelang_'+ this.value);$('#limesurvey').submit();;

NONTRIVIAL: innerHTML identifier:
/scripts/jquery/jquery-ui.js
This script is detected as nonfree, external, and as defining functions or methods:
/scripts/jquery/jquery.ui.touch-punch.min.js
This script is detected as nonfree, external, and as defining functions or methods:
/upload/templates/mint_idea_striped/template.js
This script is detected as nonfree, external, and as defining functions or methods:
/scripts/survey_runtime.js

But I suppose it would be necessary to review all the .js files and the embedded javascript code.

The information about LibreJS is here:
http://www.gnu.org/software/librejs/

I would like to help to solve this issue; however, it involves "touching" the license information in the files for rewriting it or adding a license paragraph in a certain format (see http://www.gnu.org/software/librejs/free-your-javascript.html ), and I wanted to check first here that it's ok to do so manually (maybe that information, now, is added automatically with some script or the files that are provided by third parties are retrieved periodically from upstream projects).
