Add Riak 1.3.1

This modifies how the `riak` and `riak-admin` scripts work such that one has to specify environment variables for where the data, log, and etc directories live.
Fix up the description a bit
haskell-pipes: use camelCase to name pipes packages, rather than separating words with hyphens
bind: update to 9.9.3-P1 to fix CVE-2013-3919
gnutls: use lzma version of tarball
chromium: Update stable and beta channels.

These new versions are introduced with this commit:

stable: 26.0.1410.63 -> 27.0.1453.93 (builds fine, tested)
beta:   27.0.1453.81 -> 28.0.1500.20 (builds fine, tested)

Unfortunately the tarball for the dev version 29.0.1530.2 isn't available at the
moment, so we're going to update it later.
