[A-5920] Spack 3.8 Released

Looking for a quite simple but complete package manager for your distribution or an efficient and daily viable alternative for the Slackware(R) pkgtools? Take a seat.

=== 3.8 (20120908)

= spackedit: handle correctly the packages given with a relative path.
(thanks to appzer0 for the report)

= spackfind: a pattern beginning with a slash can describe an absolute
path.

Currently, the project is under heavy development, so some features are just partially implemented and some compatibilities issues can be met in certain commands.
