Better newsteller parser

[pandusonu2]

This requires a need of little data structures and good grasp of BASH commands.

The news teller just parses the main page and displays the title and chapter and displays each line. Things which can be done

• Arrange all of them acc. to .fav file
• Parse such that multiple chapters of a title appear in single line instead of multiple lines
• Add a specifier to specify number of releases to be parsed
