Improved logging & new timeout features

• Added a --verbose option that increases the amount of information output when running the tests.
• Requests are numbered so that they can more easily be associated with response lines.
• Added new config options timeout and failOnTimeout. timeout is the max total request execution time and failOnTimeout allows a script to return a success status even if responses timed out.
