Change `if` function stack ordering, add some basic math ops to Int, add factorial example * `if` function stack ordering is changed to use condition, if-false, if-true (bottom to top). This is so we can pass a value on top of the stack directly to a new `if` in a condition, so we don't have to store a new value in a new variable. * Add __splat__ and __minus__ functions to Int * Add * and - builtins, which call the __splat__ and __minus__ functions of the top stack item, respectively. * Add factorial example because now factorials are possible with this skeleton implementation, albeit a little hacky with the recursion.
