+	JNLPRuntime.config changed to proper singleton.
+	* netx/net/sourceforge/jnlp/config/DeploymentConfiguration.java: added
+	field with getter rand setter to save loading exception.
+	* netx/net/sourceforge/jnlp/runtime/JNLPRuntime.java: (config) field is no
+	longer initialized in static block, but on demand in (getConfig).
+	(initialize) no longer load (config). (initialize) call to 
+	KeyStores.setConfiguration is using (getConfig) instead (config).
+	(getConfig) is initializing and loading (config), marking exception and sterr
+	it in case of debug on. Made synchronized.
