Remove contrib
The contrib directory takes too much of the pacman developer's limited time, which could be better spent developing and reviewing patches for the primary projects. The community can pick this up in a separate repository if wanted. Signed-off-by: Allan McRae <allan@archlinux.org>

-A flexible pacman cache cleaning utility.
-
-Usage: ${myname} <operation> [options] [targets...]
-
- Operations:
- -d, --dryrun perform a dry run, only finding candidate packages.
- -m, --move <dir> move candidate packages to "dir".
- -r, --remove remove candidate packages.
-
- Options:
- -a, --arch <arch> scan for "arch" (default: all architectures).
- -c, --cachedir <dir> scan "dir" for packages. can be used more than once.
- (default: read from @sysconfdir@/pacman.conf).
- -f, --force apply force to mv(1) and rm(1) operations.
- -h, --help display this help message and exit.
- -i, --ignore <pkgs> ignore "pkgs", comma-separated. Alternatively, specify
- "-" to read package names from stdin, newline-
- delimited.
- -k, --keep <num> keep "num" of each package in the cache (default: 3).
- --nocolor remove color from output.
- -q, --quiet minimize output
- -u, --uninstalled target uninstalled packages.
- -v, --verbose increase verbosity. specify up to 3 times.
- -z, --null use null delimiters for candidate names (only with -v
- and -vv).
