New tabs!

Took me a little while, but I have a new tab menu going. Looks the same at first glance as the last one but now there are drop down menus for Music and Video bringing you directly to the Uncertain Sound and Dead Night Sky pages of each. Also, the Dead Night Sky and ReGeneration tab open those websites in a new tab now. This is the first of a few other changes I'm planning on making for this website and was also to test a new menu system for ReGeneration after Volume 1 is over.
