Order story titles with method

[mizaki]

Closes #8

[mizaki]

Finally (and obviously in retrospect) the order of the story titles is in id from the gcd_story table. After timing the "json" and "window function" against the "Vertigooo2" method, the "Vertigooo2" method ended up being the fastest. Below are the other two.

Window function:

SELECT gcd_issue.id AS 'id', gcd_issue.key_date AS 'key_date', gcd_issue.number AS 'number', 
                gcd_issue.title AS 'issue_title', gcd_issue.series_id AS 'series_id', 
                gcd_issue.price AS 'price', gcd_issue.valid_isbn AS 'isbn', 
                gcd_issue.notes AS 'issue_notes', gcd_issue.volume AS 'volume', 
                gcd_issue.rating AS 'maturity_rating', gcd_story.characters AS 'characters', 
                stddata_country.name AS 'country', stddata_country.code AS 'country_iso', 
                stddata_language.name AS 'language', stddata_language.code AS 'language_iso', 
                (
