Undocumented path property required in security_directory

[Garrett Smith]

mod_security relies on a 'path' property in a security_directory. If
this property isn't available, you can't unblock blocked users.

Refer to line 453 of mod_security_server.erl.

E.g. a config like this:

  {security_directory,
                  {"/",
                   [{data_file, "security.dets"}]}},

will list undefined for the directory in the list of blocked users:

[{"me",any,8080,undefined,{{2011,3,11},{22,8,3}}}]

Config like this:

{security_directory,
                  {"/",
                   [{path, "/"},
                    {data_file, "security.dets"}]}},

however, will work fine.

I suspect that 'path' was supposed to be added implicitly to the
DataDir proplist during the 'store' operation in mod_security, rather
than require the user to explicitly configure it as in my example.
