Allows for a different mporting

Allows for a different mporting

Instead of

require 'yast'
m = YaST::Module.new("Foo")
m.hello

We do

require 'ycp'
require 'ycp/foo'
YCP::Foo::hello

Much nicer and the symbols are declared so
you can even ask the module for its methods

Minor other improvements.
Calling is broken for now
