Jazzman.jp improvement: it works fast!

The improve-made application has now installed, making usual response a lot faster. Now it returns within 1 second, from 3 seconds a week ago. You may sometimes see response slower because of the way memory uses at a hardware level, but I take as a reasonable one.

There is no additional function installed. However, there is an update: you now see cleaner artist name on URL when you click an artist name. It sounds not impressive, but it makes applications more secure.
