Update Category & Language value from new base json

[manimaran96]

Implement the new Spell4wiki base json

Here,

• [x] language_wise_data values refer to existing language response.
• [x] category_common array values store into shared preference set.
• [x] language_wise_data.category add into db.
• [x] language_wise_data.category if exist then only add all category otherwise add only common category. (change need here)
• [x] update title_of_words_list key instead of title_words_without_audio

• https://commons.wikimedia.org/wiki/Category:Files_uploaded_by_spell4wiki_in_ta

Note : Files_uploaded_by_spell4wiki is main category. Currently we created sub category page only for Tamil. So, other language need to create their sub category page. So, by default use main category(category_common).
