network debugging + pic shopping

- avoid remote reset: use WDT
- central power gives panic switch
- use a standard bus protocol for comm (I2C ...)

The 18f1220 doesn't have I2C, so it might be better to go for a
different component. Lowest pin count is 28. Let's take the one with
the most memory to have some room for tables and delay lines. I'm
thinking about

18f2620:  64kbytes flash, 3968 bytes ram (maxed out)

This is also a nice target for a standalone language. These are the
same, with some things missing.

          EEPROM (b)     FLASH (kb)
18f2620    1024           64
18f2610    0              64
18f2525    1024           48
18f2515    0              48
