Application Actions show keyboard modifier underscores

[Cassidy James Blaede]

App's quicklists can have an underscore modifier in the name for keyboard navigation in menus. For example, the lp:minecraft .desktop has the following:

[Desktop Action Screenshots]
Name=_Screenshots
Exec=xdg-open .minecraft/screenshots/

This is interpreted and rendered properly in plank with an underline under the "S", and keyboard navigators can hit the S key to select that action.

However, Slingshot simply shows the "_" in the string, which looks janky. Screenshot attached of Plank's and Slingshot's respective UIs using the Minecraft launcher.
