Comment 49 for bug 204567

In user-dirs.defaults, currently DOWNLOAD=Download. Setting DOWNLOAD=Downloads is more consistent with the plural form folder names in $HOME:

Plural (the rule):
  Templates
  Documents
  Music (arguable)
  Pictures
  Videos

Singular (exceptional cases):
  Desktop: Special case, corresponds to a place.
  Public: A bit strange. Maybe "Shared Items" is better, but I digress.

The DOWNLOAD directory contains discreet entities of a common type "Download". There are possibly many entities of type "Download" in the directory, so the folder should be called "Downloads".

Additionally, Mac OS, Windows Vista, and Windows 7 use a directory called "Downloads" so switchers may be slightly confused when they are looking for "Downloads" and see "Download" instead.
