[dl-ticket-service] Plus signs in file names

[Kelvin Smith]

I'm just getting started with DL, and overall I really like it. However, 
I'm surprised and disappointed to see that in the filename of a 
downloaded file, all spaces have been converted to plus signs (+). I 
know that spaces can be problematic in web addresses and the like (thus 
the common display of %20 in the middle of addresses), but I've never 
run into this issue for a file download before, whether using a hosting 
service like Box or when simply downloading an ordinary file from a web 
page.

A workaround is to put the file into a zip archive, and I sometimes do 
that anyway to save space and upload time. But I wonder why it's necessary.
