1.7.9 BATTLE ART

This is just a minor update to fix ROM sprite transparency for mons like pikachu, jigglypuff etc. Crystal sprites still work.
It also recolors the Battle HUD HP bars in COLOR and INVERTED mode to be brigher green, yellow, red as they deplete.
One important update was also to make UNLIT sprite light mode, and ARENA FILL: WHITE disable self shadowed sprite.

I will be investigating a PRERELEASE 1.8.0 with precaching for voxels and a black loading transition after exits/loading.
Version 1.8.1 has a more precooked version available from the Title screen "Precache", but it tends to be overwritten...
