Patch for Fedora package

Description of problem:
Whenever instance of urxvt (or urxvt256c) is started either form run dialog or as a result of being assigned to a shortcut key, a new app icon pops up. However, if I start urxvt/urxvt256c from applications list (as via corresponding *.desktop file), the matching is mostly correct.

Adding StartupWMClass to *.desktop file solves the problem (patch for Fedora package included)


Version-Release number of selected component (if applicable):
gnome-shell-3.10.2-1.fc20.x86_64
rxvt-unicode-256color-9.19-1.fc20.x86_64
rxvt-unicode-9.19-1.fc20.x86_64

How reproducible:
always

Steps to Reproduce:
1. start rxvt unicode from dashboard
2. see that an entry with a nice terminal icon appears
3. alt-f2 and start another urxvt
4. observe a missing icon in applications list, not grouped with previous urxvt instance

Actual results:


Expected results:
