wip... move to a installable structure
portability: /bin/bash might not exist on some systems

On *BSD bash is not installed by default. Use the /usr/bin/env
to find a copy of bash.
wip..
configure: Enable parsing of --prefix
git: Really ignore vim files
misc: Share the code to resolve/create the PIDFILE path
start-image: We know where to find bootstrap.st do it that way
misc: Create a working example with the launch.d with symlinks

The README will be included and compiled so just specify it
as a Smalltalk comment.
install: Fix prefix, add sysconfdir, generate Makefile for install

For installing the package we generate a Makefile that honors
the DESTDIR variable and can now build proper packages.
debian: Create a minimal debian package
