Added '-s' to test a specific server url
Got rid of our generic "error handler" and just logging more descriptive errors right from the return result
* Added flag to select a specific server by ID (instead of by url), added display of sever id to '-l' and to other displays of the server name - https://github.com/zpeters/speedtest/issues/2
* Not panicing on Latency check fails, instead setting the latency really high. Testing of multiple servers will continue and the "slow" server will naturally get dropped out of the list - https://github.com/zpeters/speedtest/issues/1
Bumped version to 0.04
