Merge the web_client_signed branch. Now the Web client communicates solely through the REST API with the server. Also, modified the hosted mode launchers a bit to pass the token as a parameter to the client.
Initialize the input & output buffers for WebDAV & REST handlers in the deployment descriptors. Also raise them to 4k in order to be consistent with the other buffer sizes we use in Webdav, FileUpload, FileDownload and ExternalAPIBean. Configuring all of them to the value of a single constant, defined in gss.properties, is left as a future task.
Initial import.
