Latest changes to the code. Changed the way RequestHandler uses Logger, ...

Alright.
As it stands, the web server runs, and logs events into the log file (shuttle.log) located in the log folder. The few minor changes I made are:
1) creating an instance of the Logger class per RequestHandler. This is because of some bugs, more log entries were being generated for each Request than required.
2) I also changed line # 126 in the WebServer.java file, to make the default location of the log file the log folder.
3) I created a couple of bat (batch files). You just have to type the names of the three different files on different command windows, to start the Shuttle server, Selenium server, and the ApplicationTesting App.
