* Fixed bug in with RNA-paths. String identifiers (i.e. some_collection["somekey"]) were not getting handled at all due to wrong indices it seems. I don't know of any other code using this, so hopefully there aren't any unintended bugs caused by this.
This means that bone animation now works again.
* Added a few more sanity checks to file-reading code, and heaps of extra prints everywhere else for debugging purposes (these will be removed in due course).
