Business Layer; object FromXML functions updated to check version

In the finPOWER Connect Business Layer, most objects that expose a "FromXML" function have been updated so that the FromXML function validates the version of the XML.

WARNING. When upgrading to finPOWER Connect 1.4.1 you must ensure all computers are running this version. If one or more computers are running older versions, ie 1.4.0 they may experience unpredictable issues.
