Ignore .svn directories and IntelliJ project files.
Implemented interactions between GwtHttpServletResponse and its wrapped
ServletResponse as per portlet spec 2.0 PLT.19.4.5.
This forwards some calls to the ServletResponse for resource requests
that weren't forwarded before, essentially enabling file uploads and
similar things.
Changed version of the bridge to 1.0.3-SNAPSHOT to fit our repository,
sorry world!
