This Fixes #799: update jquery to 2.*

Upgraded jquery from 1.10.2 to 2.1.1.
I have done smoke testing on almost all features and found nothing is broken.
@sneha-bharti / @Arko2013 : Please do a thorough regression testing on all features.
Make sure you do a clean build and clean your browser cache before testing.
Let me know if you find anything is breaking.
