pptp-linux

Requests that pptp-linux be available on the CD, since it is required for
some users to get access to their ISP.  pptp-linux is currently in the
SupportedSeed.

Shall we add it to BaseSeed, or only to ShipSeed?

Looking at the package, it is very simple, essentially just supplying
/usr/sbin/pptp.  As such, it should be quite safe.  We currently include
ppp, pppoeconf, etc. in the BaseSeed with similar justifications.  However,
PPTP is not as commonly needed, and perhaps ShipSeed is sufficient.

Thoughts?
