Progress!

I finally got the 'else' statement finished and working, so now entire decision structures are working including scopes.  I also implemented built-in functions.  They are fully functioning with return values (or no return value) and multiple arguments.  However, I have not yet tested overloading and there is no user defined function option yet.  Lastly, I implemented while loops.  They are probably the simplest loop structure to implement but it provided a nice a framework for do...while and for loops.  After I implement those last two loops I will implement some engine specific things such as states and events.  After that it will be a fully functioning scripting engine!
