Created kie-swagger-ui project to create separate Swagger UI war

This was actually super easy: 

1. add maven war plugin to pom.xml
2. add files from swagger-ui dist directory (after checking out 2.0.24 tag)
3. add empty web.xml
4. Make minor fixes to the index.html

..and voila! 

BTW, I'm not sure what you did with my other pull-request, but I don't think it made it into this branch.. (etirelli/swagger) :) 

(Don't tell Mark I did this frontend work, though.. ;D ) 
Ahh!!! thanks, good to know.
