Make group and owner options work correctly for untar.

--group and --owner do not work when uncompressing files. This is for compressing file only :/
Changed the way we set the owner by seting it to the user that runs the untar.
  - --owner and --group do not work as i thought they do.
included the deploy class by default in the definition
- This is not strictly correct but it catched a lot of people out
remove line
update travis file
