Cleaned up editables code.  Added generator editable checkbox on anchors (default true) and knots (default false). Generator status is stored in XML metadata. Improved performance of the layout engine. Adjustable calculations can be selected and masses/charges set for all entities (slower). Preparations for cloud connection.
