Update for nodepicker icon

The supplied icon for the nodepicker is a small drupal icon (v6x-1.5). It would be a clearer interface if this suggested a link to a page. I attach a suggested icon made from the TinyMCE link chain over a page.

I assume that the licence should be OK - but I'm not an expert. The chain presumably falls under Moxiecode's LGPL;

I modified the page from one of the Tango Icon Library - open source:
http://tango.freedesktop.org/Tango_Icon_Library

I'm happy to give over this modification under an open licence if required.

But perhaps someone can do a better job? (The PSD file is attached also in the ZIP file).
