Packaging tools

The "post-build event" script in the PJSE project relies on a few non-Microsoft tools. All are from SourceForge.

They are:

tar - GNU tar from unxutils, version 1.12 (not 1.13) (http://sourceforge.net/projects/unxutils)
grep - GNU grep from unxutils, version 2.5.1 (http://sourceforge.net/projects/unxutils)
7za - 7-Zip command line archiver, version 4.42 (http://sourceforge.net/projects/sevenzip)
makensis - from Nullsoft Scriptable Install System, version 2.21 (http://sourceforge.net/projects/nsis)
