Fix (#139) - Tweets are not getting loaded on artists page
Fix (#150) - Reviewer page fails for Shubha Shetty
Fix (#149) - Photos, songs, cast are already commented.

Removing the unnecessary commented code. The crawling for photos and
songs is handled from other part of code.
Fix (#155) - show top nav bar on hover

Facing small issue in hiding the nav bar on lost focus. It was creating
bad user experience. Hence left it as it is.
