Removed/disabled NTSC from design, as the tiny HDMI monitor is practically always used. Also greatly increased L2 cache size, although no performance benefits for the relatively small programs I currently use for benchmarking.

Integrated valid bits into cache block ram. Reset now iteratively clears the entire cache. Allows for much lower FPGA usage and better timings. Should be able to greatly increase cache size as there is an abundance of BRAM.
