Increment 'pkgrel' numbers for all packages.

Here's what was run:

    for p in */PKGBUILD ; do
        awk -F= '{ if(/pkgrel/){ a=$2 ; a++ ; print "pkgrel="a } else { print } }' \
          $p | sponge $p
    done
Add 'find-package' script.

This script looks for a package in BlackArch, ArchTrack, the official
repos, and the AUR.
find-package: Add 'Does not exist' possibility.
Add 'list-needed' script.

This script lists dependency packages that we need to pull into
BlackArch.
list-needed: Add hard dependencies.
list-needed: Add ArchTrack checking.
list-needed: Strip package version specifications.

This removes the '>='s the and '<='s from the ends of package
dependencies.
Move 'list-packages' to 'list-groups'.

This name makes more sense.
list-needed: Unset optdepends and depends each time around the loop.

This speeds things up a bit.
list-needed: Clear up potential variable ambiguity.
Add 'list-loose-package' script.

This script lists packages that aren't in groups and aren't dependencies
for other packages.
redfang: Add to groups.

This adds 'redfang' to the 'blackarch' and 'blackarch-wireless' groups.
list-loose-packages: Make output more parsable.
pack: Remove the auto-generated 'TODO' comment.
edb: Add to groups.

This adds the package to 'blackarch' and 'blackarch-reversing'.
nikto: Clean up. Add to groups.

These changes should have been made on merge.
samdump2: Remove an old TODO comment.
sipvicious: Add to groups.
sqlninja: Add to groups. Clean up.
sqlsus: Remove old TODO comments.
