- Fixed logging module
  * delete obsolete and unused code from KIWILog
  * make sure error log messages are printed on stderr
  * delete obsolete --log-port option
- Delete git from Recommends list in the spec file
  SUSE by default installs all recommended packages which
  increases the amount of software installed when kiwi is
  installed by an unnecessary number of packages
- Update bash completion
  Added possible options for --upgrade
- Fixed typo in message texts
- DB: rebuild documentation
- Improve logging of errors for session scripts
  kiwi creates session scripts running in screen logging all
  output to the kiwi logfile. In case of an error we only want
  to see the stderr information and not the entire history
