Suggestion: Add database column for source category

[alserembani94]

The idea is, to filter list of dua based on several categories:

• Type of sources - Quran, Hadith, others (maybe dua sahaba, etc.)
• Specifics of sources - From Ibn Ahmad, or from Sahih Bukhari, Sahih Muslim, etc. Especially for hadith, one dua can have multiple sources

This will help more scholars to improve the searching in the future. Though we already have sources, we might need to consider this implementation. For example, have another table to store sources info, and need to cater for many-to-many cases, since one source can have multiple duas, and one dua can be found in different sources.

What do you guys think?
