Subject: [PATCH] =?UTF-8?q?UI:=20Pretty=20Atmosph=C3=A8re=20mod=20names=20?=
 =?UTF-8?q?(#601)?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Changes the mods from the Atmosphère folder to show a pretty name
instead of just the name of the folder they're in, because those names
are always just a title ID.

NOTE: The DLC names are from the file names, not retrieved from the
content file itself like the main applications.
