Base/kernel upgrade basically works.  I am not sure if we should
immediately trigger the reboot in this case.  OTOH, some might
ignore the obvious reason to boot the new kernel that had just
been aqcuired.  At least it's stable now and not easily killable
through the GUI reload anymore.  :)

* Abbreviations are generally discouraged in persistent
  menu items.  They look unprofessional or plain sloppy.

* Items should be short and concise.  One word if possible.
  Always avoid doubled meanings like e.g. "HA" + "Sync".

* "Manager" this and that everwhere is simply annoying.

Adapted the the GUI layout and rewrote the curl probing in PHP
while at it.  Many thanks for the initial code donation and idea!
