GENCLIENT-308 Implemented a very simple UI for creating and editing User
Group.

  currently only editing user group based on Organization is supported.
  The Description, E-Mail, (De)-Activation and type is not yet
  implemented.

  If the an existing User Group has a lot of Organization, then the
  UI can be slow. Because we have to fetch every Organization in order
  to get its title.
Merge branch 'GENCLIENT-308'

Minor: Reformat source code and update license header

  Reformat source code using escidoc-codestyle. The Maven Java Formatter
  Plug-in is not work as expected. It does not completely format the
  source using the eSciDoc code style.

  Some of the file has outdated copyright year, i.e. 2011. The Maven
  License Plug-in automatically updated to 2012.
