Sprites.

I spent the last few days on working on the sprite loading / display.

My code is 90% complete but of course, completly untested for now.
It will probably take sometime before I post new pictures including those.
The sprite code amount for 20% of the whole design, and 70% of the generated logic in the FPGA.

Once I have finished that, I have a lot of small details and things to finish.
The TODO list is maintained inside the SVN anyway.
