Blind fix for billing report crash

Somehow we're getting tasks with new_subtitle_version=None again.
Still no clue why this happens, but I'm guessing that calling
get_subtitle_version() should fix the issue of the billing report
generation crashing.
For issue #1080, make the title clickable for edition, initialize it with video title if no subtitle title exists and finally find a way to style the whole thing
For issue #1080, init title in modal as well, and improve size of text areas
For issue #1080, move speaker-name above the description
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.
For issue #1080, tentative for additional step in workflow, only valid in translations
