improve extension development by using some DSL features

[jdwije]

The extension API could be streamlined and thought out more. It doesn't have to be perfect but this might be a good opportunity to try out the DSL features of ruby.

Whilst I'm not in favour of the instance_eval() which yields a block like API akin to:

Class::new do |c|
  c.title = "xxx"
  c.desciption = File.open("xx.txt")
end

I do like the idea of modifying the core ruby syntax to be a bit more Lewt Extension tailored within the context of a LEWT Extension. For example the options & the command could be set like this:

MyExt < LewtExtension
  options ++ :param { 
                :default => false, 
                :definitions => "what this option is about",
                :type => String
                }
  command :my_command
end
