This allows us to put other internal data in there in the future. Also passing it through the Node constructor properly now. * ve.dm.Node ** Rename fringeWhitespace property to internal ** Add internal parameter to constructor ** Remove setFringeWhitespace() * Increase the number of parameters passed through by ve.Factory to 3 * Pass through .internal from linmod to nodeFactory in ve.dm.Document * ve.dm.Converter ** Rename .fringeWhitespace to .internal.whitespace and make it an array ** Store a temporary reference to .internal in domElement.veInternal * Add internal to all node constructors except TextNode Tests: * Update for fringeWhitespace->internal rename * Add third parameter to ve.Factory tests * Add .internal to getNodeTreeSummary Change-Id: If20c0bb78fee3efa55f72e51e7fc261283358de7
