Bug in script of app.js is fixed which was giving error in webkit browsers and site's rendering was getting affected.

**Error :**
If any one could have noticed in firebug site was giving error. Still code was working fine in *Firefox*.
But when we come to Web-kit browser's like *chrome*, some of the js dependent apps like Observation was not working (map was not appearing).

**Resolved :**
The script for menu bar was giving error. This script was for hide/show behavior of menu bar. That we are not using right now. So the code is commented and error is now resolved.
