Poll: -pre, -post, multiple -f/-g

[Stan Shebs]

I'm working on improvements to networking, and ran up against a
couple of features that make it hard to integrate command-line and
GUI-based network game setup.  These are the -pre and -post options,
which allow one to specify GDL forms on the command line, and the
ability to use -f/-g more than once and have Xconq load all of them
in order.  In retrospect, these kinds of features are more appropriate
for programming tools than user tools, and I don't think anybody uses
them - you can always get the equivalent by spending about one minute
to create a new module.

So unless somebody makes a strong case to keep -pre, -post, and
multiple -f/-g, I'll remove them.
