I agree this is annoying and something I wanted to fix. Some obvious ideas:

0. Compute mimetype on file upload and set this on download

Note this is done automatically by remote backends like Google storage
and S3. Wouldn't be impossible to do.

1. Include the original filename in the filepath.

Problem: for remote backends (google storage etc) we don't know this
file when we submit file for upload from upload form and hence cannot
find out where the file exactly was uploaded to (so we can't do things
like put a nice url for it when you return to CKAN or create a
resource -- or do anything post upload!)

2. Allow users to specific a filename for upload

Problem: for remote backends this requires that we regenerate the
authentication policy which requires some javascript to regenerate the
upload form policy doc each time users edits a field (not impossible
given that we do have the auth form api ...). Does have advantage you
could allow other fields (e.g. mimetype to be added).

Other key improvements (that sort of relate):

* Automatically create a CKAN resource for the uploaded file (and
allow association to a package)
* Allow users to overwrite their own files (which would require us to
stop auto-generating filepaths)
