General cleanup and fixed a buffer overrun bug. It may be necessary to normalize filter gain differently or something.

Made a very significant optimization to the FIR filter which I believe I can take a little further. Right now the FIR filter size is 768 and I get some free() bugs, so this is something I need to debug.

The windowed sinc filter generation code seems to be working fine. The FIR filtering code is also now working reasonably well. Occasionally the FIR filter will pop, but setting the normalization factor lower seems to help this. I suspect the problem is in the fixed point multiply/add. I also have a hunch the zero stuffing/sample discarding code is not correct, and I'll look at that soon to get it sorted out.

Cleaned up some bugs, but the FIR filter is still distorting.

Fixed lots of bugs in FIR filtering. Fixed point code is closer to working, but there seems to be overflow in the FIR filter resulting in distortion.

IIR filtering now seems to work fine. Fixed point code also seems to be good.

Implemented a lot of fixed point code for the filters. The SDL_FixMpy functions currently don't work properly -- there are some issues with signed vs unsigned.
