Update torsocks to version 1.3

We moved torsocks away from Google Code and back to the Tor
git repository. We also fixed a number of bugs and released
version 1.3.
Add tlsdate

This adds tlsdate to homebrew. In theory release 0.0.6 will support
OS X out of the box and so I have included the latest tagged release
as well as a --HEAD target. One must use --HEAD today on OS 10.8.2
or better.

When this patch is merged, I will update the tlsdate documentation
in master of the tlsdate git repo to instruct people to install
tlsdate with homebrew rather than doing it by hand.
Add makedepend utility

This adds a very simple replacement for the otherwise unpackaged
and essentially required makedepend utility. This tool is missing
on Mac OS X 10.8.x and without it many packages, such as modern
OpenSSL, will simply refuse to build without hackery.
