• write-tree: Hash the files

Instead of only printing the file name, let’s put all files in the object database. For now we’ll print their OID and their name.

Notice that instead of getting one OID to represent a directory we now get a separate OID for each file, which isn’t very useful. Plus, note that the names of the files aren’t stored in the object database, they are just printed and then the information is discarded.

So at this stage write-tree isn’t useful (it just saves a bunch of files as blobs) but the next change will fix it.
