[cai18n-dev] Type safe message definition

[Ceki Gulcu]

Hi Takeshi,

Thank you for sharing your new ideas. I just cloned 
http://github.com/takeshi/cai18n/tree/master.

It looks like MessageDefinitionConveyor is referencing the class 
ch.qos.cai18n.sample.ColorMessageConfiguration (part of the tests). This causes 
the maven build to fail for me.

I'll look at the code some more tomorrow morning and come back to you with comments.

Cheers,
