Added AllForOne to close child processes

Added AllForOne to close child processes (webdrivers and IisExpressWebServer). Should be merged correctly with ILMerge.
Addressed issue with ChromeDriver displaying "You are using an unsupported command-line flag: --ignore-certifcate-errors. Stability and security will suffer."
