Refs #4041, allow all view/visualization properties to be set via query parameter, remove unecessary client side properties from ViewDataTable, move HtmlTable specific client side parameters to HtmlTable, remove code that looks for generic filter query parameters when setting client side parameters, make sure client side parameters are set if they're not false (ie, 0) instead of if not empty and add filter_offset as view property.
