[Adium-devl] JSON framework

[Peter Hosey]

We first added the JSON framework before 2.0 was released. Now, it's  
not only hit 2.0, it's all the way up to 2.0.1.

Meanwhile, we've been maintaining it ourselves separately all this  
time, committing our own fixes. And I'm not sure that we've submitted  
them all upstream.

I'm of the opinion that we should bulldoze our copy of the framework  
sources and replace them with an svn:externals reference to the 2.0.1  
tag in the JSON framework. 2.0.1 even already has a crash fix that I  
just committed to our own repo earlier today.

For any future JSON framework releases, we can simply change the  
svn:externals property to refer to a different tag; then, we  
automatically get the new release, without having to commit its entire  
source code to our own repository.
