Add three Formulas

I've attached three formulas to this pull request. I'm the upstream for all three projects.

torsocks is now bumped to version 1.3 and is re-targeted against our git repository. We have moved away from Google Code. This is an important update as it merges a number of fixes and solved a number of patch fragmentation issues.

tlsdate is a parasitic network time utility. It is the default ntp-like client for ChromeOS; I'm also the upstream author of it. I just finished porting tlsdate to Mac OS X in the HEAD of master and I wanted to ensure that users could have a secure and easy way to install tlsdate: homebrew seemed the obvious answer.

makedepend is a small shell script to help satisfy a number of build dependencies. I'm the upstream author of this version of makedepend (which isn't saying much). This will allow people to build certain versions of OpenSSL and other tools the Tor Browser on OS X. Previously, I had to use macports and I'd rather use homebrew to satisfy all of my build dependencies. I believe this will be moderately useful for a number of people.
