pirtidy - call for help

[Will Coleda]

There is a start at a pirtidy perl script at tools/utils/pirtidy.pl,  
using lib/Parrot/PIR/Formatter.pm, tests at t/perl/ 
Parrot_PIR_Formatter.t

There are a bunch of skip'd tests, some notes in the perl module  
listing some more possible things to be done.

This mainly requires perl knowledge, with some understanding of PIR  
syntax.

I have a few other things on my plate and probably won't get back to  
this soon.

Regards.
