Jangle Core PHP scripts now in SVN

[Ross Singer]

Hi everybody,

I've crudely ported the Jangle Core to PHP now as well. It's what's
running at http://demo.jangle.org/

In the SVN repo, it's in the PHPCore subdirectory.

It desperately needs caching (well, and rewriting, frankly), although
its slowness at the moment is due to our cheap shared webhost.

Eventually the Jangle classes from the Core and the Connector libs
will be merged (since they're more or less the same structure).

-Ross.
