[GeneX-dev] executable not directory, fixed

[<ja...@op...>]

Hey All,

I've just committed the change to the installer so that it won't
accept directories for any apps.

I think we want to re-write GetOrSet() and GetOrSetGNU() to be the
same methods. The code is nearly identical, it's just the the GNU apps
have an extra --version check.
