Fixes Issue #14

When uploading files, students will now be shown an
error message if there upload would replace already existing
files.

This upload will not be performed until it will not clobber
any old files.

Note that there is currently a way to change this behaviour in
the code in action.py, to allow files to be overwritten. However
there is no way this flag can be set through the browser interface
(yet).
