Incremental update

Hello!

I've put together an incremental update to the demo to get certain features I personally value into peoples' hands sooner. The update is available for the Windows and Mac version. I'll upload the browser version later or at request.

Here's what's changed:

• The battle backgrounds have been updated, and Dark Pegasus's "fortress" has a different battle background from the rest of the dungeon.
• Because DMFA has so many hand-to-hand fighters, fist weapons are now available. These include brass knuckles, claws, and so forth. They can be equipped by Dan, Abel, Wildy and Biggs. Whips have also been added to the code, but not implemented until there's a character that needs them.
• Abel has been reworked. He still has Gloom Wave and his general statline, but he now has a secondary attack spell called Thunder Flash, a different casting animation, and a few other changes.
• Certain music cues have been adjusted.

Cheers!
