Support custom x509 TLS Certificates

This release adds the -cert flag to vegeta which enables the usage of user-provided certificates for HTTPS requests.

Memory improvement

This release removes some unnecessary memory overhead.

Local address, better timeouts, slicker APIs

This release includes three improvements:

• Now one can specify which local IP address to use.
• Timeout now includes connection timeout as well as response timeout.
• Attacker API simplified to be immutable by passing all required state through NewAttacker instead of setters.

Bug fixes

This release fixes two bugs:

• Command line header flag values can now contain colons.
• vegeta.NewMetrics accepts an empty Results slice without panic.

Some bug fixes

• [@tredman] Fix Vegeta plot labels
• [@xla, @tsenart] Include response body transfer time in latency results

Request body, improved CLI usage

This release includes the option to specify a request body in the attack command as well as better usage output of vegeta -h.
