Fold the _rights dictionary into params

Fix bug where script fails when it encounters a socket (which is not a regular file). Fix bug where exception is raised if error occurred before parser object was returned from _buildParser(). Add a --notext option, so that just the file paths will be output on matches (both find and find/replace); useful with xargs. Patch by: Todd Larsen

Fix user key stuff Key field for user is now link_name, instead of account, as such the method's used by 'create new user' should be updated.
