Add window for running arbitrary privileged JavaScript

Browse source 
This is a replacement for the Execute JS extension that could be used
with Zotero for Firefox.

To enable, go to the Config Editor in the Advanced pane of the
preferences and set devtools.chrome.enabled to true, and then restart
Zotero. A "Run JavaScript" option will appear in the Tools menu.
