[patch] Script for installing OptionalPackages from within a current installation

[mmadia]

This is a bare bones, born out of necessity idea. Essentially it allows end users a controlled method for installing OptionalPackages from within Haiku.

optpkgman is the name of the CLI application

Usage: ./optpkgman.sh [-l] [-a]
-l      List installable packages
-a      Add a package and all of it's dependencies

There are many flaws to this method. But it may be better than having end users manually install an incorrect optional package, as the correct version and it's dependencies are installed and have any symlinks created.

The script will determine the revision of Haiku and use that to download the appropriate build/jam/.... files from svn.

I'm attempting to implement this as an independent bash script.

Attached the current work in progress. I'm considering importing more of build/jam and having this script to jump start jam.

I haven't worked on this in a while and don't see being able to in the near future.

Even though the PackageFS is in the works, I had an itch for shell scripting. Will submit an updated script in the next few days.
