Changed a massive swap statement for bounds checks

Instead of using a massive block of case statements in serial_utility.cpp,
I've added FORMAT_* tags to SerialPacketType as a way to destinguish
between type values, at least internally. I can't believe I missed this
for so long.

I've also added a placeholder for the network API, as I was working on
that when I ran into this problem.
