Search all providers

[jneidel]

All current providers, except readmng, have a search option available per get request (%s for query):

• mangareader: https://www.mangareader.net/search/?w=%s&rd=0&status=0&order=0&genre=&p=0
• mangalife: https://mangalife.us/search/?keyword=%s
• goodmanga: http://www.goodmanga.net/manga-search?key=%s
• mangainn: http://www.mangainn.net/advanced-search?term=%s (click search button to trigger search)

For a search interface via cli a search property should be added to all providers. This search prop takes a query and returns the results of the search. The function should request the above specified urls with the query and then scrape the results from the resulting html.

Results should be presented with Inquirer as a list from which the user can choose which manga to download.

Example:

naruto 			 mangreader - 700
naruto-shippuden mangalife  - 566
