Support for PORTA pin changes (>28-pin ATmegas) about arduino-pinchangeint HOT 6 OPEN

Sorry, I missed this issue!  I will look at your changes and roll them into the 
code, same as I did for the MEGA stuff.  But it will require you to debug it 
for me.

Sure thing, I'd be happy to test out any changes on the '644pa board I have
:-)

It's been a while and as you can see this is not a high priority for me. One 
issue is that I don't have an ATmega that uses PORTA, so I can't really test my 
code. And I have other projects that are taking my time (not least of all, 
work...). 

So this *may* get fixed but unless someone tackles it, it won't be soon.

I've been using the patches above on the '644-based Mosquino project for some 
time now without problems (have not formally tested it against other 
Arduino/chip variants however). That version with the patches applied is 
available at 
http://code.google.com/p/mosquino/source/browse/#hg%2Flibraries%2FPinChangeInt 
in case anyone has time to do such testing. (May be identical to the version 
attached above)
