Added CONFIG_SYS_FWVER and CONFIG_VCP_RS232C_ENABLE #3

CONFIG_SYS_FWVER: Changed location of hardcoded defines in jtag.cpp. Current setting is slightly higher than "Curiosity Nano" FW. This avoids MPLAB-X version upgrade notices when emulating pkobn. (Of course, it fails if you try.)

CONFIG_VCP_RS232C_ENABLE: You can now disable the GPIOs for RS232C compatible signals on the CDC-ACM. This frees up to 6 pins for user applications.
