deploy resource does not add "--no-auth-cache" to the svn command line arguments

The deploy resource does not appear to add the --no-auth-cache to the svn command line arguments. This is a problem because in the default configuration, svn will presents an interactive prompt asking the user whether they want to save the password to disk. This can be worked around with the "svn_arguments" option, but I think it would be better to add it by default. (I think it's only the "deploy" resource that has this problem, not the "subversion" resource.)
