Updated Javadoc documentation.

Fixed erroneous initialization of editors that remained open from the
last session when Spotter Service is not online on startup. Now only a
blank page with an error message is shown.

Fixed "invalid thread access" tooltip bug.

Fixed some bugs in AddExtensionsDialog in case when Spotter Service was
offline. Additionally the dialog will not open anymore when there is no
connection.

Deleted no longer needed class SimpleExtensionsRenderer.

Reworked navigator viewer elements. Updated context menu, so "Open",
"Duplicate" and "Delete" are now content aware.

Added context entry "Open" for elements that can be opened in the
navigator.

Implemented possibility to delete Run Result nodes in the navigator.

Improved update process of Results. When selecting Run Result nodes the
Results View is only changed if the node actually changed.

Fixed focus bug in editors.
