Upgrade Jquery in Bioviz site to remove console errors and warrnings

Fixed console log errors which were appearing due to migration of Jquery from 1.1 to 3.3.1 version.

Please add link to branch.

Questions:

• This code: script src="js/libs/modernizr-2.5.3-respond-1.1.0.min.js" is now script src="//code.jquery.com/jquery-1.11.2.min.js" Can we now remove this and other .js files from the repository since we are now getting them from jquery (and other) CDNs ?
• Why does src="//code.jquery.com/jquery-1.11.2.min.js work? There is no "http:" in front of //code.jquery.com/jquery-1.11.2.min.js

Ans1) I just moved src="js/libs/modernizr-2.5.3-respond-1.1.0.min.js" in scripts section to load when other scripts are being loaded. Its not a replacement to src="//code.jquery.com/jquery-1.11.2.min.js". modernizr plugin is not a part of jquery. So we cannot remove that plugin.

Ans2) If there is no protocol specfied before the src, then browser uses the same protocol which is used for loading that html file (http or https).
So, its okay to not specify protocol and the code still works in any case.

Task related to this task are locally made and they are not present in the branch yet.
I will make the changes to the branch once I have IGBF-1288 merged to master (because there might be code change in same files and it might lead to conflicts).
So to save time, I have worked on the files locally.
Once I have changes on the branch, I shall provide a link to this issue.

Completed changing the actual files for upgrading Jquery.
Branch : https://bitbucket.org/swathark/bioviz/branch/IGBF-1305

It also minor js changes related to upgrading jquery.

Assigning it to Prof. [~aloraine] for review.
