[ENH] VMMaker overwrite files and unix success (with a few problems) (was: v2 first release now available)

Here is a final cleaned up version. A few fixes, plus I use the FileMenu to
ask for a saveConfig file.
I got the unix version to build and run, with BitBltPlugin internal. I get
a failure to load the Security module because of an undefined symbol:
#ioCanDeleteFileOfSize. When I build with all plugins external, the display
never refreshes and I get a continuous output of the SecurityPlugin failure,
until a stack overflow of some kind.
2 other problems under unix. As Tim points out in the source, file copy
doesn't preserve file permissions. therefore, you have to chmod the
The other problem is that when we regenerate the vm on top of a prior vm,
with different plugin plans, then the old plugin files for internal plugins
stay in the prior location and the Makefile attempts to compile them in both
places. We ought to delete plugin files that change their modularization,
so we can keep the src hierarchy curent.

It currently does *not* ask a 'do you really want to do this' kind of
question. Use at your own risk. I tried regenerating a vm on top of a
previous generation and it asks for every file. ugh. so I ported this code
and fixed up all of the #newFileNamed: calls in your changeset.
> In other news, I generated a unix tree with all plugins external. This
didn't compile for me - it couldn't find main(). :-( It looks like the
sqXWindow.c needs to be statically linked to the binary. Is there some set
of plugins that are best left internal to get my main?
