[gcs-pcs-list] new Greasemonkey script

[Alf Eaton]

Here's a new Greasemonkey script for processing COinS:
http://alf.hubmed.org/openurlcoins.user.js

It's very simple and doesn't try to convert from 1.0 to 0.1, but it  
seems to be working ok on <http://ocoins.info/>, Wikipedia  
Booksources pages and abstract pages in HubMed.

As a default setting, it links to the SFX demo server to resolve the  
OpenURLs.
