For CSS files, use getResourceAsStream in cssfetcher

[dbs]

The public pages use a CSSFetcher class to feed in the stylesheet from the con_details table. They also use a 'starter' web.css file before loading via the fetcher.

The fetcher should load the default web.css file, then feed the local customzations out to the JSP engine, rather than use 2 lines in the JSP. That way we can alter themes within Coconut by changing which css files are fed out to the pages without having to alter the local files.
