Started to use a process filter for the svn output

* trunk/contrib/client-side/psvn/psvn.el:
  The process filter will be used to implement a way to read username/password
  from the user.
  svn-status-use-process-filter: New variable to activate the new process filter
    It is set to nil because it could potentially break every psvn functionality.
  (svn-run-svn): Install the process filter if needed.
  (svn-process-filter): New function. It receives the output from the svn process.
    It inserts the output to the *svn-process* buffer and shows the chunks in the
    *Messages* buffer for debugging purposes
