kie-issues#208: Renaming any "NamedElement" on the DMN Editor should update all references to the old name

[danielzhe]

Closes: apache/incubator-kie-issues#208

Some comments about the changes:

• We are tracking now all changes performed in BEE reported to DMN Editor. For now, we only have "special treatment" for the Action.VariableChanged;
• A big part of the changes are related to this. Don't panic. It is just an indentation level that can make the PR bigger than it really is;
• In the lower levels of the code, I refactored from "variable" to "identifier", because those objects are not only variables but identifiers;
• I added documentation to a few methods and classes.

Renaming Data Types

Data.Types.mp4

Renaming BKMs and parameters

Bkm.and.Parameters.mp4

General rename

Some.Renames.mp4

Renaming Included Models name
It does not show the confirmation dialog, because doesn't make sense to not update the references in this case, since this already was the default behavior before this PR (when we renamed a included model, we already updated all the references except the expressions, now we update the expressions).

Included.Models.mp4

Just a typo.

Thank you for the PR @danielzhe. It's going to take me a few days to go over everything with the care it deserves. Will keep you posted!

@danielzhe Storybook is pointing to code using ../src because it is used during development. The changes you introduced will make the development experience much worse, requiring us to rebuild stuff after a change, if I'm not mistaken... can you please check?
