RNA

* Added RNA for operators. This still uses ID properties internally,
  but through the RNA API now. The OP_get/set_* API that was used is
  replaced by the RNA API. Currently RNA properties for operators are
  defined at runtime since it means operator registration can be done
  in a single function.
* Changed the existing operators to use this system, I haven't defined
  user interface names yet though. I also think there need to be some
  conventions on which properties to expose to make these operators
  usable in macros, for example if mouse coordinates should be stored
  or not.
* When using ID properties through defined RNA properties, it now
  checks that the ID property actually matches the RNA property and
  removes/overwrites it otherwise. This ensures that you can safely
  get/set arrays for example without having to worry that some
  external thing may have changed the length.
* Documentation now has some information on RNA + ID properties.
