On-the-fly file type switching.

@jankeromnes, want to take a stab at a review?

If I understand correctly, calling file.writeMeta will call driver.dumpMeta and then resetType. This will then in turn call driver.loadMeta, try to guessType or default to binary (always overwriting the previous type), and then call file.writeMeta again if file.meta.type of file.meta['Last-Modified'] are undefined, restarting from the beginning.

Won't that recurse unnecessarily? Aren't we risking infinite callback loops? Why overwrite the file's type every time you write metadata to disk?

From what you said, we'll always end up with a file.meta.type set, won't we? And it will be set once for every file anyway. Unless another program systematically resets the metadata file, it won't loop indefinitely.

Great, thanks!
