[Pki-devel] [PATCH] 446 Added general configuration page.

A new page has been added to manage general TPS configuration properties. The properties are read-only by default. In edit mode the property name will become a link which will show a dialog to edit the property value. The config REST service has been updated to use PATCH for update operation and handle possible null collection of properties. Fixed a bug in TableItem.reset() where the code didn't clear the table cell properly. Fixed a bug in ConfigDatabase.getProperties() where the code didn't handle null property key properly.
