[pptp-server] Update + patch

[Stacy Lindberg]

My mppe config now works...with windoze clients anyways.  Thanks to Pascal
and Emir.

I've made a single patch for ppp-2.3.10 that should simplify the process
of getting mppe to work.  Here's where you can grab it.  

null.home.dhs.org/ppp-2.3.10-openssl-rc4-mppe-stateless.patch.gz

I've tested it a couple of times...other than that, just follow the Howto
directions, and skip the other patches.

One problem, I couldn't get the NTS Tunnelbuilder client for Macintosh to
work with the mppe encryption turned on in the client.  It works with no
encryption just fine.  Here's the unsupported protocol errors.
