Last time I made quick hack to support PIC18, I introduced a few bugs along the way. I ironed it out and added support for a few new devices, namely PIC12F1571 and 1572, as well as LF version of the same. Similar PIC devices should be easy to add. I have to add changes that @webwicht made in previous log.

Sources are on github, as usual. Old sources were removed, now ouy have pp3.c (compile as per instructions in this howto) and pp.ino (arduino sketch) as the only two sources you need.
