Tried to do some better commenting in usb_serial.c, also tried to do a better job of documenting the protocol in programmer_protocol.h

Did some more splitting of responsibilities in the code

Moved the programmer protocol to a different file in preparation for sharing it across all the various programs (bootloader, programmer, control program)

Added extra commands for moving back and forth between the bootloader and the actual program.
...
Disabled the flash erase capability on the main program while I'm working on the bootloader...

Fixed a tiny mistake -- forgot to say the name of one of my enums after the typedef.
...
Finished making the electrical test work -- I had failed to realize that I have to ignore the ground shorts once they have been found -- otherwise they reappear against EVERY tested pin (because they are always low and I'm testing for low pins -- duh!). Anyway, it was showing way too many shorts, and that's why. Now I independently can find shorts between separate pins without getting flooded with the ground shorts too. Only thing that's missing is the VCC shorts, but I can't do that without pullups (to my knowledge)

Started implementing electrical test that tells what pins are shorted to what

Fixed a bug with how many bytes I was allowing to be written. It mostly works but it writes the chips in reverse...oops

Started working on more optimizations, but something weird is happening and it's crashing...not sure why yet.

Added electrical test option to my temporary command line.
...
Also experimented with skipping the SPI -- I left my test code in there, commented out, in case I want to do some more speed testing.

Started getting writing working, as well as the ability to restrict to a specific set of chips to write to

Created read and write cycle functions, along with a block read function. I think this will look better...
...
I also changed the port module so it doesn't needlessly update the data direction register over SPI if it's being told to set the same value it had before.

Finished testing the new functions I made for chip identification. It works well

I got the device identification working, and I'm in the middle of breaking it into its own set of functions for write cycles, read cycles, unlock sequence, etc.

Fixed a few stupid bugs -- it's now reading data correctly.

Continued playing with USB serial stuff. I think it's working well now, but I'm running into problems reading from the SIMM, so I need to figure out why I'm not getting the data I expect.
