Added new formaula for librcsc and soccerwindow2

librcsc 4.1.0 and soccerwindow2 5.1.0

librcsc: the library for Robocup soccer simulation.
soccerwindow2: the debugger for Robocup soccer simulation.
soccerwindow2 is dependent on librcsc.
BTW, how do I specify both source files in a formula that installs both?
