RNA minor changes
* Added start of lamp wrapping (code by Michael Fox).
* Add back Object.data, was crashing with unknown data type.
* Added support for using consecutive variables like float r, g, b;
as an array without writing a manual get/set function.
* Also note the RNA documentation is updated now to be more
about how to define RNA and use it, including some diagrams.
