Title: Made download filename more reliable (#1133)

Switched to using a whitelist approach where we only allow certain
characters and remove the others. Switched from replacing characters
with "_" to simply removing them. This is what django's
get_valid_filename() does and I think it will probably lead to nicer
looking filenames in general.

--jdragojevic tested locally works and no regressions found.
