Started trying out the JTAG loader.
Added Xilinx jtag loader tools (windows, 32-bit only)
Removed component declarations because I remembered how to not have to do that crap.
Reworked the SSD blocks and added a wrapper that decodes a nibble input and outputs a hexadecimal character
Reworked the CRG block and removed the serial baud shot counter
Mostly formatting of the VGA block
Reworked the PS2 wrapper ports (combined control / status signals into their own registers)
Added an input debouncer from OpenCores (http://opencores.org/project,debouncer_vhdl)
Wrapped the KCPSM3-supplied UART blocks
Added a block that does KCPSM port IO mapping
Modified toplevel to use the new blocks and register mappings
Rewrote the picoblaze code (still testing-mode code)
