[Kde-bindings] const_missing method in ruby 1.8

[Richard Dale]

>From the ruby 1.8 release notes:

': constants lookup

  improved at the performance of searching by using an internal hash
  table.

  calls const_missing method of the class/module, if constant is not
  found in the look up path.'

So it does look as though it will possible to trap references to to 
const_missing for constants in QtRuby. Then the Qt::Widget::MYCONST syntax 
can be used rather than Qt::Widget.MYCONST.
