Added MyTimer class, TimerTimeout interface and TestTimer class in interfaces and utilities packages. Also added two sound files as resources. For more details check commit notes and comments on github (click on commit and scroll down). I didn't do any work in app_logic and user_interface packages, so the same problems remain from last commit.
