Rudder

By fixing http://www.rudder-project.org/redmine/issues/3599, we enforced correctly content of variable name in the technique CFEngine Generic Variable Definition

However, it appears that the "dot" in the variable name is not considered an error by CFEngine if in a bundle common, hence exactly in the case of this techniques ( http://www.rudder-project.org/redmine/issues/3640 )
So we must provide a script to "fix" this "regression" by replacing "dot" by underscore in the variable name in directives based on Create a migration script to "undot" variable names in CFEngine Generic Variable Definition, and of course in the directives using these variables
