fix(rest): seperate creation of rest fatjars to maven profile

[maierthomas]

• removed the auto build for fatjars in rest projects
  --> added maven profile to obtain the option to build rest fatjars

closes #799

[mcjaeger]

maybe testing could be like this using the fatjar:
java -jar myfatjar.jar

[maierthomas]

Yes you can run the fatjar (wars) successfully with java -jar resource.war/authorization.war
In general if someone needs this fatjar war files the user can generate fatjars with maven profile parameter fatjar.

maven package -P fatjar
This command will generate package.war (fatjar) and package.war.original (no fatjar, no main manifest)

I think we should describe this options in the readme or wiki page.
