Plist fix may affect old XML plists

[Francisco Tolmasky]

Chances are this won't affect you, but we just fixed
http://cappuccino.lighthouseapp.com/projects/16499-cappuccino/tickets/81-xml-plist-parser-chokes-on-some-values#ticket-81-2.
This means if you had been hacking at plists extensively previously,
and they were encoded by Cappuccino in XML format (instead of 280N
format), AND they used certain special characters, they may be decoded
a bit funky. For example, "hello<" would now come out as "hello%3C"
after the update. Fixing this is pretty straightforward, you could
manually change it yourself, or simply encode into 280N format before
updating, then encode back to XML format after updating.

The good news is that we are now complain with real plists on Mac OS X
so there shouldn't be encoding troubles anymore when using Property
List Editor to edit your plists on macs.

Let me know if you have any trouble with this either here or in IRC
and I'll help you fix any issues.

Thanks,

Francisco
