Fixing issue #4: Incorrect name sent to Sauce Labs for job.
Add py.test marks to Sauce Labs tags.
Set context for Selenium RC to the test name.
Put debug in a subdirectory.
Only output links and screenshot if they exist.
Make the Base URL in the report a link.
Added failure details, removed additional table row for tests that pass, and removed check for debug files existing.
Added name and tags improvements to WebDriver Sauce Labs tests.
Moved gathering of network traffic and added to the custom report.
Improved configuration reporting for Sauce Labs.
Added capture of log for debug.
The log may contain passwords, etc so we shouldn't capture this until we can do so safely.
Added link to Sauce Labs job and embed video in report.
Fixed issue #7: More verbose assertion failure when checking response code of base URL.
Made Base URL the first command line option.
