New formula: sshtrix

sshtrix is a very fast multithreaded SSH login cracker. It supports
SSHv1 and SSHv2. sshtrix was designed to automate rapid bruteforce
attacks against SSH authentication screens. Unlike other public tools,
the aim is to keep it simple, stable, fast and modular. With its clean
code design, it is easy to extend the code to a framework or to fork it
against protocols of your choice.
