CPS3 Emulator Preview Test version

This is a preview version of my CPS3 emulator. Here you
can see the current work-in-progress state of the emulation.

There are still a lot of missing features to emulate properly
so don't report any emulation errors yet. The missing features
include (and the effect caused by them missing) :

Sprite Zoom: you'll see the sprite tiles (squares) not being properly aligned or with gaps
Fullscreen Zoom: Sometimes it seems like the camera is not pointing to the action
Per-tile palette selection: some colors (a lot in some games) are wrong
Priorities: objects that are over the background when they should appear behind
Linescroll: Floor 3D effect missing. SF32ndi scrolling letters in intro missing.
Linezoom: I don't know where is it used :)
