mavenization and i18n

standarization of code

I'm just curious about draw widget from this project, and I need to test i18n from scratch. 

Not expected you really need to merge this, but here you are.

NOTE: translations are far from finished. 
NOTE2: I choose org.m2 as package (maybe better org.2m)
I do not think exception messages should be i18nized. It does not trickle up to the GUI, does it?
