Added new fields to Melodies model to offer additional information on the raag

[irvanjitsingh]

Proposing additional fields to the Melodies table that will contain additional information on the raag, of a musical nature. This information is crucial for the individual reading/singing a given shabad who wishes to sing it as prescribed by the Guru. A suggested and reputable datasource would be vismaadnaad.org (an example can be found here: http://vismaadnaad.org/Siree-Raag.php)

Also, as an aside, since some shabads in Sri Guru Granth Sahib Ji have also been assigned a 'ghar' (tabla taal), a complete database ought to account for that information as well. A table such as Rhythm would work, although most shabads would get a null value for associated Rhythm.

This is a good idea! However, I would prefer that if you're including a pull request that it's included with the final data for the melodies table as I will not have time to populate or work on this. I can though connect you with the necessary people/trained Kirtanis if you wish to undertake this fully to get to the final set of data.
