Version 2.0.4.rc1

A release candidate for 2.0.4
- https://dwr.dev.java.net/servlets/ProjectDocumentList?folderID=9081

I've painfully done nearly 50 test combinations of browser/server/dwr mode today, and 2.0.4 is passing, at least for me.

The one thing left un-done is fixing an iframe remoting memory leak. I thought I'd got a fix, but the bug remains. As far as I know it only affects IE6 without ActiveX, so 2.0.4 might slip out without it...
