Finish Range implementation

[troyhen]

The following needs to work:

0..10 == new Range(0, 10, true)
0...10 == new Range(0, 10, false)
0..10@2 == new Range(0, 10, true, 2)
(0..10).each def num
    num.println              # prints 0, 1, 2, 3 to 10 on separate lines
?a..?z == new Range('a', 'z', true)
'a'..'z' == new Range("a", "z", true)
