Gitaroo Man merge

Found separate pages for Gitaroo Man and its PSP remake while browsing. Seeing as Gitaroo Man Lives is to the original what War of the Lions is to Final Fantasy Tactics, I'm thinking it'd make sense to merge the two pages.

Here's Gitaroo Man
Here's the PSP re-release

Fixed this, and added releases for both, as well as transplanting the info from the PSP page over to the PS2 page.
