GNOME Client: Hardcoded icon path in launcher file

Issue generated from Tuleap's migration script. Originally submitted by: Vincent Bermel (willov)

Currently in the launcher file gnome-ring.desktop.in the icon path is hardcoded to the following absolute path:

Icon=@RING\_INSTALL\_PREFIX@/share/icons/hicolor/scalable/apps/ring.svg

This prevents icon theming without editing the launcher file.

According to the freedesktop.org standard application launcher icon locations are:
/usr/share/icons/hicolor/[size]/apps/
\~/.local/share/icons/hicolor/[size]/apps/
/usr/share/pixmaps/

Since you already install your icon to a standard location according to the standard specification and w.r.t. the icon lookup mechanisms of GNU/Linux DEs you can change the icon path line to simply the icon name:

Icon=ring

You needn't specify the full path or the file extension for icons in a standard location.

The icon will still up correctly and additionally can be themed via globally applied themes.
