Updated user guide.

* Added Maciej Baluta's GCI work on NetworkStatus, PowerStatus and
  ProcessController with only minor changes.
* Created a page for Daniel Marth's GCI work, based on the wiki page at
  https://dev.haiku-os.org/wiki/SystemBinCommands
* Updated translations mostly for Japanese and Italian from the currently 
  running GCI tasks.

Thanks everyone!
