[R] place 4 ini files

[Prof Brian Ripley]

Please do read what "writing R extensions" says about the data directory.
This is not a correct use of that directory, and may well fail in the next 
release.

I suggest you install them in an ini directory, by putting them in 
inst/ini in the package sources.

That makes assumptions about where a package is installed.  Use 
system.file(), e.g.

source(system.file("ini", "foo_ini.R", package="__pkg__"))

See the discussion of `inst'.
