New multiline conditions and class/interfaces/enum declaration

[Peekmo]

Major changes

Note before : I took decisions to write this code, you could like it, or not. If you don't, close it and that's all ^^

The "Conditions.rx" is the most complete example for all the changes added in this PR :

class self < String :: TestInterface

def self.main()
  def myvar : String = null
  def myarray = Array<String>.new()

  if myvar != null && myvar.charAt(10) == "p":
    for i in myarray.iterator():
      trace("Wouhou")
    end
  elsif myvar != null && myvar.charAt(20) == "c":
    trace("no")
  else
    trace("coco")
  end

  if myvar == null
     && myvar.charAt(0) == "x"
     && myvar.charAt(2) == "x":
    trace("ok")
  end
end

What's new ?

• I set python styles for conditions, in other words loops and controls must be ended by : (and so, multiline is managed properly)
• self class is replaced by class self to be more natural for everyone (no value added with the inversion)
• < is like ruby, it represents inheritance and will be replaced by "extends"
• :: is replaced by "implements"
• abstract class, class, enum and interface are working
• You can write class MyClass instead of class self (both are valid)

In the code :

• I added \n in the tokens, it's needed for class declaration
• Also added <, ::, , (:: is added before to be parsed before : of course)

Hope you'll like it.
