Redirect to the other wxruby homepage?

Hey hanmac - in case rwx is no longer maintained, would you consider
adding a link to the README to the new wxwidgets bindings?

[AndyObtiva]

The new wxWidgets Ruby binding is at:
https://github.com/mcorino/wxRuby3

There is even a new software-engineer-friendly Ruby DSL for it called Glimmer DSL for WX:
https://github.com/AndyObtiva/glimmer-dsl-wx

I am happy that the rwx project re-ignited the fire for maintaining the wxWidgets Ruby binding, and that carried on in the wxRuby3 project.

in thinking about wxRuby3 i might even want to reignite rwx, there are even some mayor differences.

like i'm still pretty sure that rwx has better memory management (and protects objects from getting deleted by Ruby or wx)

as for the other links, i will add them to the Readme soon if able
