Flying V lives!

I've been working on good old 'V again. Here's some of it's lovely new features!

- Horizontal panning added
- Player/enemy bullets sprites redrawn pixel by pixel
- Difficulty settings have been re-enabled, including fake 'bullet hell' ones, like in XYX
- Death's Head LUNA (level 2 boss) has a second attack phase and her wings are now destructible.
- MEGA MEDAL mode (difficulty 7), where stray enemy bullets turn into medals and the scoring potential goes through the roof!
- Old music tracks are being scrapped. Many thanks go to those who helped me with them, of course; but I'm aiming for greater consistency and refinement overall. Raigon mentioned possibly working on some music for this; but I won't hold him to it.

I've asked SSK to help me with a video for the new version, too, so keep an eye out. :)
