Additional fields in MVC library

This module was used in the old XMLRPC client code, but is no longer
needed.  Removal was escalated by FreeBSD when the oniguruma4 dependency
of the php56-mbstring module was marked BROKEN.

We're moving PPTP back, the whole discussion is rather pointless
to be honest.  We'll make it a plugin for 16.7, I think that's
only fair for users who know what they are doing.

Dormant ever since 2009, time to remove those finally.

They are replaced by the navigation.  Log files need to be cleaned
up further.  Progress is good.  :)
